I am in the process of implementing a LoanBroker with Mulesoft but have an error message when sending a request. I get the following error message back from Postman and Mulesoft Anypoint Studio:

Can anyone help me?

This generally happens when one tries to access inner value of a payload like json but incoming payload is NOT actually a json type.
One could check the payload mediaType and then try to access the amount in order to avoid Value Selector exception.
%dw 2.0
output application/java
---
if( !isEmpty(payload) and payload.^mediaType contains "json" )
payload.amount
else
read(payload, "application/json").amount //best effort
Would recommend creating a separate dataweave file like dwl/set-amount.dwl and referencing it.
You are probably sending some body in the HTTP request from Postman but Mule doesn't know how to read it. Maybe you did not the Content-Type header in the request to let DataWeave know it is a JSON (application/json) or XML (application/XML).
Ensure you are sending the right content type.
I ran into the same situation. I know exactly the base64 is a json. So, I tried to set the MIME Type by
<set-payload value="#[payload]" doc:name="Set Payload" mimeType="application/json"/>
It works for me.

I'm using lnav to filter and query on top of the custom log file we have created.
As this is a custom log file, I need to create a custom format file and install it using below command to define the structure of the log entries.
lanv -i custom_format.json
Custom format JSON: https://pastebin.com/z7sCVqxd
Though this is working at the high level, I would also like to apply filters using the parameters that are present in body JSON.
The body parameter I've mentioned in the custom formatter is JSON. Not the entire log entry is JSON but only the body parameter value alone is the JSON., In the body parameter only the log level, message and other useful information are present.
Is it possible to use something like,
"level-field" : body.level,
"level" : {
"error" : "error",
"warning" : "info"
},
And also how to define other parameters from the body json to Value for defining "kind" and "identifier" or not
Thanks
So far I've analyzed I couldn't find any direct solution. I went through the documentation of lnav (here) and found out that there are few JSON functions available which we can use to extract the data from JSON based columns.
with mylog as (select jobserver, workqueue, processid, jget('{"' || col_0 || '"}','/LEVEL') level, jget('{"' || col_0 || '"}','/PREFIX') pid, jget('{"' || col_0 || '"}','/MESSAGE') message from logline) select * from mylog where processid = 358812 limit 1
This temporarily solved the problem. But I'm still looking for the support from lnav API itself.
I'm facing a problem with loading the Sitecore Commerce Business Tools on my local machine. I don't get any error in my browser which you can check on the following screenshoot, but the page is not initialized:
Seems like the operations GetNavigationView() and GetLanguageView() are stuck on getting data, but I couldn't figure out what could be the problem.
As preparation steps, I did the Sitecore Commerce Bootstrap, and Environment Initialization via Postman and everything went ok.
In the CommerceAuthoring_Sc9\wwwroot\config.json I set up the certificate thumbprint and here is what I have in the AppSettings:
"AppSettings": {
...
"SitecoreIdentityServerUrl": "https://localhost:5050",
"AllowedOrigins": [
"https://localhost:4200",
"https://sxa.storefront.com"],
"AntiForgeryEnabled": false,
"UseHttpsInKestrel": true,
"SslPort": 5000,
"SslPfxPath": "wwwroot/localhost.pfx",
"SslPfxPassword": "sitecore"
}
Also in the CommerceAuthoring_Sc9\wwwroot\bootstrap\Global.json I added all the environments I use.
Here you can check some of the errors I noticed in the CommerceAuthoring logs:

I checked some solutions that were already mentioned across the forums but no luck fo far.
I'll very appreciate if you have any advice for me!

After some time, we got the following error on the UAT env. but I'm not sure if we can do a Commerce Bootstrap there without losing our data:

Also, the storefront item 'CommerceEngineDefaultStorefront' exist in the database that is specified in the PlugIn.Content.PolicySet-1.0.0.json file. I feel some of the json files has invalid params/values or the formatting is wrong, but I couldn't find any lead, furthermore, they haven't been changed recently.

Eventualy, it appeared the our CD was down for some period.
How to pass parameters to datamapper in mule and access them. (In XSLT, I pass them as context parameters, receive them in param and access using $ symbol). I need to do the same thing in datamapper. Any suggestions/links/example are appreciated.
Approach1:
We are using invokeTransformer method in datamapper
output.abc= invokeTransformer("MyTransformer",input.abcdef);
This MyTransformer is a java component which has this default method overridden.
#Override
public String transformMessage(MuleMessage message, String outputEncoding)
throws TransformerException {
System.out.println("Inside transformer" +message.getProperty ("sessionVariable1",PropertyScope.SESSION));
return message.getProperty("sessionVariable1",PropertyScope.SESSION);
But, the problem is I am not calling this transformer from mule flow. But, invoking it from datamapper. Hence the argument 'message' does not get passed. So, Unable to retrive that session variable to return to datamapper. Is there a way to send this argument(MuleMessage from datamapper)?
You can use input arguments with DataMapper and then refer to them in the output:
<set-variable variableName="testvar" value="value of testvar"/>
<data-mapper:transform config-ref="new_mapping_grf"">
<data-mapper:input-arguments>
<data-mapper:input-argument key="testvar">#[flowVars['testvar']]</data-mapper:input-argument>
</data-mapper:input-arguments>
</data-mapper:transform>
and
output.myField = invokeTransformer("MyTransformer",inputArguments.testvar);
or
output.myField = inputArguments.testvar;
Adding input arguments available in the DataMapper GUI through the input side green plus icon.
OK, I think there's no easy (make that lazy) way to do what I want but given the Perl SOAP::Transport::HTTP::CGI code fragment below what I am looking to do is intercept all SOAP operation passing through the service and log the result of an operation or fault...
SOAP::Transport::HTTP::CGI
-> dispatch_to(
#first arg needs to be the directory holding the PackageName.pm modules with no trailing "/". The args aftre the first are name of SPECIFIC packages to be loaded as needed by SOAP requests
#Failure to call out specific moudules below will allow the external SOAP modules to be loaded, but the overall module #INC path for other Perl modules will be blocked for security reasons
SOAP_MODULE_INCULDE, #name of the directory holding the PackageName.pm modules with no trailing "/"
"TechnicalMetaDataExtraction", #prod - wrapper for EXIFTool
"Ingest", #module (package) name
"ImageManipulation", #module (package) name
"FacebookBroadcast", #unfinished
"CompressDecompress", #unfinished
"ImageOCR", #prod - tesseract
"HandleDotNet", #prod
"Pipeline", #prod (needs work)
"TwitterBroadcast", #prototype
"Messaging", #prototype but text format email works
"Property", #development
"FileManager", #prototype
"PassThrough" #prod - module to do location conversion (URL -> Fedora Obj+DS, Fedora Obj+DS -> file, URL -> InlineBase64, etc.) but format conversion
) #done with the dispacth_to section
-> on_action(sub {
#on_action method lets you specify SOAPAction understanding. It acceptsreference to subroutine that takes three parameters: SOAPAction, method_uri and method_name.
#'SOAPAction' is taken from HTTP header and method_uri and method_name are extracted from request's body. Default behavior is match 'SOAPAction' if present and ignore it otherwise.
#die SOAP::Data->type('string')->name('debug')->value("Intercepted call, SOAP request='".shift(#_)."'");
if($Debug) {
##_ notes:
#[0] - "http://www.example.org/PassThrough/NewOperation"
#[1] - http://www.example.org/PassThrough/
#[2] - NewOperation
#[3] - "undefined"
my %DataHash=(
message => #_[0]
);
#SendMessageToAMQTopic(localtime()." - ".#_[0]);
SendDebugMessage(\%DataHash, "info");
} #there's only one element passed at this level
}) #end on_action
#-> on_debug() #not valid for SOAP::Transport::HTTP::CGI
#-> request() #valid, but does not fire - request method gives you access to HTTP::Request object which you can provide for Server component to handle request.
#-> response() #does not fire - response method gives you access to HTTP::Response object which you can access to get results from Server component after request was handled.
#-> options({compress_threshold => 10000}) #causes problems for the JavaScript soap client - removed for the moment
-> handle() #fires but ignores content in sub - handle method will handle your request. You should provide parameters with request() method, call handle() and get it back with response().
;
Initially I thought I could get the information I needed from the "on_action" method, but that only contains the destination of the SOAP call (before it is sent?) and I'm looking for data in the operation result that will be sent back to the SOAP client. The documentation of "SOAP::Transport::HTTP::CGI" is a bit thin and there are few examples online.
Anyone know if this is possible give the what the code above is set up? If not, then the only other option is to alter each method of my SOAP service code modules to include the "SendDebugMessage" function.
I would suggest subclassing SOAP::Transport::HTTP::CGI and hooking into the handle() method. An untested and probably non-working example would be:
package MySoapCGI;
use Data::Dumper;
use SOAP::Transport::HTTP;
use base 'SOAP::Transport::HTTP::CGI';
sub handle {
my $self = shift;
$self->SUPER::handle(#_);
warn Dumper($self->request);
warn Dumper($self->response);
}
Replace the dumpers with whatever logging you want. You may need to do some XML parsing, because these will be the raw HTTP::Request and HTTP::Response.
I have an ASP.NET webservice and some of the fields in the request are defined as enums. When entering a blank or invalid value, the response comes back as:
Parameter name: type ---> System.ArgumentException: Must specify valid information for parsing in the string.
at System.Enum.Parse(Type enumType, String value, Boolean ignoreCase)
at System.Web.Services.Protocols.ScalarFormatter.FromString(String value, Type type)
--- End of inner exception stack trace ---
at System.Web.Services.Protocols.ScalarFormatter.FromString(String value, Type type)

at System.Web.Services.Protocols.HtmlFormParameterReader.Read(HttpRequest request)
at System.Web.Services.Protocols.HttpServerProtocol.ReadParameters()
at System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest()
Is it possible to capture errors like this and return an XML based response instead?
No, there's no way to do this with ASMX web services.
Naturally, you can do this with WCF.
Of course, it would be better if your client sent valid data. You might want to find out why they aren't.
Sure, it would look something like this:
try
{
Enum.Parse(Type enumType, String value, Boolean ignoreCase)
}
catch (ArgumentException e)
{
//Serialise exception information from 'e' into XML
//(not shown here) and set it as the response
Response.Write(xmlMessage);
Response.End();
}
