You have specified an Apollo key but have not specified a graph ref; usage reporting is disabled. To enable usage reporting, set the APOLLO_GRAPH_REF environment variable to your-graph-id#your-graph-variant. To disable this warning, install ApolloServerPluginUsageReportingDisabled
I am struggling to find instructions for how to 'finish' the setup for an apollo classic graph. All of this worked fine last week but no longer does (I can see on Apollo's instructions page that something changed on 4 Oct and maybe requires people to change their graph reference).
I'm trying to solve these problems one step at a time, but cannot make sense of the instructions for apollo.
The format represented in the error message has two fragments, separated by an 'a' symbol. The format of the apollo key in the federation 2 instructions also has two fragments, but they are separated by a colon.
To find your-graph-id#your-graph-variant, log in to the apollo sutdio, got to settings and under the This Graph tab, look at the first section of General settings, you should find your-graph-id.
The variant is usually defaulted as current, i.e variant=current. If you have specified a different variant, be sure to use it.
In your .env you'd have to specify these two keys:
APOLLO_KEY=<your-apollo-api-key>
APOLLO_GRAPH_REF=<your-graph-id>#<current-or-your-variant>
Restart your server and you should be good.

Is there a way to get the list of all the versions of a specific resource created in FHIR store. I have used the following call,
<FHIR_URL>/<resource-type>/<resource-id>/_history
but its not returning response
If I add version to this url:
<FHIR_URL>/<resource-type>/<resource-id>/_history/<version>
then it only shows that particular version of the resource, but all the versions of a specific resource are required, is there a way to get this?
When in doubt, I always try the reference-implementations.
(all GET requests below)
http://wildfhir4.aegis.net/fhir4-0-1/Patient/example/_history
https://vonk.fire.ly/R4/Patient/pat1/_history
http://hapi.fhir.org/baseR4/Patient/616330/_history?_count=50
I got each systems Patient-Fhir-Logical-Id ("example", "pat1", "616330") by using the search function, and picking a random Patient. The Search function is as simple as /Patient/? and no query string values.
While always subject to change and "re doing the seed data", the aegis example above (today) is returning multiple rows of history for a single patient.
If AWS does not work "mostly the same" as the 3 reference implementations, I would submit a bug report.
But based on your examples, it seems to fall in line with the reference implementation examples above and the HL7 documentation below.

I am learning Kubernetes recently, and I am not very clear about the difference between "kubectl apply" and "kubectl replace". Is there any situation that we can only use one of them?
I have written up a thorough explanation of the differences between apply, replace, and patch: Kubernetes Apply vs. Replace vs. Patch. It includes an explanation that the current top-ranked answer to this question is wrong.
Briefly, kubectl apply uses the provided spec to create a resource if it does not exist and update, i.e., patch, it if it does. The spec provided to apply need only contain the required parts of a spec, when creating a resource the API will use defaults for the rest and when updating a resource it will use its current values.
The kubectl replace completely replaces the existing resource with the one defined by the provided spec. replace wants a complete spec as input, including read-only properties supplied by the API like .metadata.resourceVersion, .spec.nodeName for pods, .spec.clusterIP for services, and .secrets for service accounts. kubectl has some internal tricks to help you get that right, but typically the use case for replace is getting a resource spec, changing a property, and then using that changed, complete spec to replace the existing resource.
The kubectl replace command has a --force option which actually does not use the replace, i.e., PUT, API endpoint. It forcibly deletes (DELETE) and then recreates, (POST) the resource using the provided spec.
Updated Answer
My original was rather controversial and I would even say now, in hindsight, half incorrect. So here is an updated answer which I hope will be more helpful:
commands like kubectl patch, replace, delete, create, even edit are all imperative: they tell kubectl exactly what to do
the kubectl apply command is OTOH "declarative" in that it tells kubernetes, here is a desired state (the yaml from the file provided to the apply command), now figure out how to get there: create, patch, replace the object, etc whatever it takes... you get the idea.
So the 2 commands are hugely different.
EG with apply you can give it just the changes you want: it will figure out what properties of the object need to be changed, and leave the other ones alone; if those properties are "immutable" (eg, the nodeName of a pod), it will complain, and if you then repeat the command with --force, it is smart enough to know to do the equivalent of a replace --force.
In general, you should favor apply (with --force when necessary), and only use the imperative commands when the declarative approach does not give the expected result (although I would love to see examples of this -- I'm guessing this would happen only when you would need several steps because of interdependencies that will have negative consequences if done with apply).
The difference between apply and replace is similar to the difference between apply and create.
create / replace uses the imperative approach, while apply uses the declarative approach.
If you used create to create the resource, then use replace to update it. If you used apply to create the resource, then use apply to update it.
Note that both replace and apply require a complete spec, and both create the new resources first before deleting the old ones (unless --force is specified).
you can add option -v=8 when use kubectl, and you will find the log like this
apply --force
patch 422
delete 200
get 200
get 200
get 404
post 201
replace --force
get 200
delete 200
get 404
post 201
kubectl apply .. will use various heuristics to selectively update the values specified within the resource.
kubectl replace ... will replace / overwrite the entire object with the values specified. This should be preferred as you're avoiding the complexity of the selective heuristic update. However some resources like ingresses/load balancers can't really be replaced as they're immutable.
Example of the heuristic update leading to non obvious operation: https://github.com/kubernetes/kubernetes/issues/67135
From: https://github.com/kubernetes/website/blob/master/content/en/docs/concepts/cluster-administration/manage-deployment.md
Disruptive updates
In some cases, you may need to update resource fields that cannot be
updated once initialized, or you may just want to make a recursive
change immediately, such as to fix broken pods created by a
Deployment. To change such fields, use replace --force, which deletes
and re-creates the resource.
I'm stuck with this problem on Master Data Service (MDS).
I have an entity that has two domain based to other two entities.
I created the first business rule with the first domain based and it works perfectly.
But when I try to create a second business rule with the second domain based, an error appears:
200095 : Cannot specify more than one entity in MetadataGet
400003 : The attribute reference is not valid. The attribute was not found.
400003 : The attribute reference is not valid. The attribute was not found.
Obviously the attribute is valid. In fact, if I delete the first business rules, the second one is published correctly.
I think that MDS block a second business rules if you try to apply to a second domain based attribute.
This happened to us as well, and it seems that this error only occurs if a specific set of actions is taken:
We first restored the MDS 2012 database on SQL Server 2017
We upgraded a database using MDS management tool. Mind that the multi-entity business rules work fine now - they return no errors upon saving, can be published and successfully evalueted
We then realized that we are missing some code changes, so we decided to create a full model package using MDSModelDeploy.exe in our old MDS 2012
We deployed that package using MDSModelDeploy deployupdate command. After that the existing multi-entity rules are failing to publish, you are also unable to create new rules based on different entities within one entity. Unfortunately, we have found no fix for it, as there are simpler ways around it.
At this point we took a step back, restored and upgraded the old database once again, and it turned out that the rules worked, so it got to be the package that has broken those. I do not know what your situation was, since when we created a fresh model in SQL 2017 all of the multi-entity based rules worked perfectly, so I am curious to know what steps should be taken to reproduce the error in your case.
The only possible approach I can think of to fix the situation in point 4, would be to create an MDSModelDeploy update package from the corrupted model and another one from a new, healthy model, and then compare how the XMLs of the multi-entity business rules are structured. We did not try this one though, since we found the workaround described previously.
We have a very weird issue in our Siebel 7.8 application.
In the Application_Start event we define a bunch of profile attributes, which determine if the logged user will be allowed to perform certain operations or not. The code is something like this:
if (userHasSuperpowers) {
TheApplication().SetProfileAttr("CanFly", "Y");
} else {
// CanFly is not set, and GetProfileAttr("CanFly") returns ''
}
Everything works fine, except for one of these profile attributes. The conditions are not met, so we don't set its value. But when we check it using GetProfileAttr... it returns 'Y' instead of ''.
I've checked the code. A lot. I've put traces everywhere, and I'm 100% sure that when the last line of the Application_Start event executes, the attribute is still empty. However, in the first Applet_Load event after the login (in the HLS Salutation Applet (HLS Home) applet), its value has already changed to 'Y'. Why!!? I've looked everywhere, but I can't find anywhere else where we'd be doing a SetProfileAttr. So far, I've ruled out:
Every browser and server script for all our applets, application, BCs and business services.
All the runtime business services (the ones defined directly in the application instead of the SRF).
The Personalization Profile business component fields.
SmartScripts (not that they would matter in this particular scenario, I just mention them to acknowledge that you can set profile attributes there too).
Workflows: every step invoking the SIS OM PMT Service method Set Profile Attribute.
Siebel magically setting its value. The profile attribute name is custom made, in Spanish, and it contains our project name and a row_id. I really don't think Siebel is using the same name for its own profile attributes :).
But wait, there is more, I left the best part for last: the problem only happens in our development environment!
It's not an SRF issue: if we promote the same SRF to our testing or production environments, it works and returns the expected value.
It's not a data problem: still with the same SRF, I can use my local thick client, connecting to our development database with the same login and password, and it works fine too.
It's not a concurrency problem: we are testing with only one user logged in. And even if we had more, they wouldn't share sessions. And even if they did, the value wouldn't be always 'Y'.
It's not a temporary glitch, or something due to a wrong incremental compilation or a corrupted SRF: we have been experiencing this for at least 6 months (obviously, in that time frame, we've had dozens of different SRF files... all of them having the same problem, but only in development, and only if you use the server and not the dedicated client... seriously...).
Where else could I search the profile attribute being set? I've read that they can be persisted to the DB, but in order to do so, you have to define them as a field in a BC based on an S_PARTY extension table, right?
Is there any way to trace profile attribute changes somehow? Maybe rising some loglevel?
How can I find out at least what's being executed after the Application_Start, before loading the first applet?
Any other ideas? I tried checking the SQL spool file too, but didn't find anything suspicious there either (i.e., any of the queries we use to check the conditions, being run twice with different parameters).
Update: following Ranjith R's suggestions, I've also checked:
Other vanilla business services which could be also invoked from a workflow to set a profile attr: User Registration > SetProfileAttr, SessionAccessService > SetProfileAttr and ISS Promotion Agreement Manager > SetProfileAttributes.
Runtime events setting profile attributes directly or using a business service (we don't have any runtime events apart from the vanilla ones).
Business services being called from DVMs (we only have vanilla data validation rules, and none of them apply to our buscomps).
Still no luck...
Ok... finally we found what's happening:
We access the URL to our server and get to the login page. This triggers a first Application_Start event, for the SADMIN user.
We set the profile attributes in that session. SADMIN is the Siebel administrator user, so yes, he hasSuperpowers and therefore we do TheApplication().SetProfileAttr("CanFly", "Y");.
The Application_Start event finishes.
We enter our username and password in the login screen to access into Siebel. This triggers a second Application_Start event, this time for our user. This is the one I was monitoring with the trace files.
We set the profile attributes again in the new session. Our user doesn't hasSuperpowers, so we don't set any value for the CanFly attribute.
The Application_Start event finishes, and CanFly is still empty.
Siebel merges both sessions into one before loading the first screen!! Or at least, it transfers over the profile attributes we had set for SADMIN.
I'm sure it happens that way, for two reasons. First, we changed the profile attribute name to include the username too. And second, instead of storing just an "Y", we are storing now the current date:
var time = (new Date()).getTime();
TheApplication().SetProfileAttr("CanFly_" + TheApplication().LoginName(), time);
We end up having CanFly_SADMIN, but no CanFly_USER, and the time value stored is the same we see in the log file for step 2... which is smaller than any of the values for the *_USER attributes.
So that's what happening. I still don't know why Siebel behaves this way, but that would be matter for another question. According to the Siebel bookshelf:
The Start event is called when the client starts and again when the user interface is first displayed.
...but it doesn't say anythign about it being called from two different sessions, different users too, and then merging them together. It must be something misconfigured in our dev environment, considering it doesn't happen in the other ones.
Does Siebel 7.8 have runtime Events? I can't recall. Runtime events have an action set for setevent, which can set/clear profile attributes.
There are still other vanilla business services which can set profile attributes, try searching in tools flat under business service methods for *rofile*tt*.
The SIS OM service can also be invoked from DVMs for from RunTime events directly, so thats also a possibility.
There is no logging system to see values of Profile Attributes changing, testing is the only way out.
we are experiencing some very odd errors in our installation.
Some times out of nowhere Sitecore throws an error:
Assert: Value Cannot be null. Parameter: Item.
The closest i have come to identifying the problem is narrowing it down to either an index or the web database.
Anyway, if I log into sitecore the Item is just missing, i can fix it in 3 ways:
Rebuild the index.
Recycle app pool
iisreset
Does any of you have an idea why this might be happening? We are running Sitecore.NET 6.5.0 (rev. 120706). Any help will be deeply appreciated.
You are describing a system stability issue, so I recommend opening a ticket with Sitecore support (http://support.sitecore.net). This sort of issue is difficult to troubleshoot over Stack Overflow, since we do not have access to your logs and configuration.
When opening the ticket, I recommend using the Support Package Generator which bundles up all the information (Web.config, App_Config files, IIS settings, Sitecore log files) that Sitecore Support needs to troubleshoot the issue. It's a pretty nifty tool.
That said, from what you describe, it sounds like the issue is related to caching. The fact that restarting IIS resolves the issue indicates that the item is in the Web database, but the runtime doesn't see it. You can prove out whether this is the issue by clearing cache using the /sitecore/admin/cache.aspx screen. If your cache is not getting updated properly, you should review your configuration against the guidelines in the SDN Scaling Guide.
Based on knowing you're using the Advanced Database Crawler, your issue may be how you're converting a SkinnyItem to an Item. I've had this issue before. If you look at the SkinnyItem.cs class, there's a GetItem() method to convert it into an Item. You can see it uses the database to get the item by its ID, language, and version number. Its possible that when you publish from master to web, you are publishing a new version # of an existing item and thus the new version exists in the web DB, but the index is not updated and references the old version. So, this GetItem() call would use the previous version # and the item would be null. One way to fix this is instead of calling that GetItem() method, just use your own code to get the latest version of that item from Sitecore, e.g.
Item item = Sitecore.Context.Database.GetItem(someSkinnyItem.ItemID);
Instead of
Item item = someSkinnyItem.GetItem();
Here's an example flow:
Foo item created in master DB as version 1.
Publish Foo to web
Index will pick up version 1 in web DB and put in index.
Any querying code against index will convert the SkinnyItem to an Item via that GetItem() method and will pass 1 as the version #.
Page will load, no error in log
Back in master, create version 2 of Foo and publish.
Index may not get updated right away or even if configured wrong.
Code that looks against index will call GetItem() and still call with version 1 since that's in the index
But when you published, web no longer has version 1, it now has version 2, and thus that specific version of that item Foo is null
Error shows in log
On a similar note, here's a blog post by Alex Shyba (creator of the ADC) on how to sync HTML cache clearing with the index updates. That may help.
