I'm getting an InvalidOperationException with no message and I'm not even sure what's wrong. Here's what's happening:
Any ideas on what's wrong?

I am trying to execute some statements within Try block. I am calling an API and performing some operations. There is one specific operation which is resulting in RuntimeError which is puked while running the program, although I am catching it with an exception. How do I go about avoiding the errors being puked from Try block?
try:
call API and perform some tasks.
encounters an error here
Except RunTimeError as ex:
print(ex)
Well as Susmit R. Veena said the point of try and except is to catch the error thrown in the try block.
In case you have some flow you want to ignore from its exceptions in the try block, than you can have a nested try catch block for the specific error you want to ignore and keep doing the logic after it is ignored.
for example:
try:
try:
call API and perform some tasks.
encounters an error here
Except TheErrorYouWantToIngore:
pass
keep on doing some stuff even TheErrorYouWantToIngore has been throwed
Except RunTimeError as ex:
print(ex)
the whole point of try and except is to catch the errors thrown by the code in try block in except block. Post the code for solution to the error

libc++abi.dylib: terminating with uncaught exception of type NSException
Is there any Way to resolve this.
Reading all the other possible solutions and apple developer documents. I have made sure to removetap and then install tap still i am facing this error.
What i am doing is i have implemented some commands in this. Once user speaks any command the application performs the action. Everything is going great but sometimes the application crashes and gives the error.
Is there any other idea about what the issue could be?
Any help will really be appreciated..
Check audioEngine.inputNode need remove when stop record. Try this code to stop audioEngine. It's the same question with this
audioEngine.stop()
recognitionRequest?.endAudio()
audioEngine.inputNode?.removeTap(onBus: 0)
I Have MQFSH as a backend,but the Queue is not yet created.
As a result the transaction is failing with an error of 2085 "unknown object".
Even after this failure , I can see there is no error rule getting triggered in the probe.
May I know the reason ?
After looking in to various blogs,got to know that
there is a settings under Advaced as " Process Backend Errors".
After setting it "Off" , the error rule started getting triggered.
Thanks & regards,

I am adding Cortana to a DirectX/XAML Windwos 10 game. Every example I can find is given in C#, not C++. Normally this wouldn't be a problem, but apparently I'm not implementing it correctly in C++ and need some help with this one.
The purpose of this chunk of code is to load a VCD file which Cortana uses for my app-related voice commands. I have already created the VCD file using standard examples.
This is the specific C# code I'm having trouble implementing in C++:
var storageFile =
await Windows.Storage.StorageFile.GetFileFromApplicationUriAsync(
new Uri("ms-appx:///myvcdfile.xml"));
await
Windows.ApplicationModel.VoiceCommands.VoiceCommandDefinitionManager.
InstallCommandDefinitionFromStorageFileAsync(storageFile);
My attempted C++ implementation of this is:
Uri^ uri = ref new Uri("ms-appx:///myvcdfile.xml");
create_task(StorageFile::GetFileFromApplicationUriAsync(uri)).then([](task<StorageFile^> t) {
StorageFile^ sfile = t.get();
Windows::ApplicationModel::VoiceCommands::VoiceCommandDefinitionManager::InstallCommandDefinitionsFromStorageFileAsync(sfile);
});
When I run this, no visible error is thrown (no immediate crash) but in the output window the following exceptions are thrown:
Exception thrown at 0x76473E28 (KernelBase.dll) in darksong.exe: 0x40080201: WinRT originate error (parameters: 0x8000000B, 0x00000040, 0x018BE280).
Exception thrown at 0x76473E28 (KernelBase.dll) in darksong.exe: 0x00000005: Access is denied.
Exception thrown at 0x76473E28 (KernelBase.dll) in darksong.exe: 0x000006D9: There are no more endpoints available from the endpoint mapper.
Exception thrown at 0x76473E28 (KernelBase.dll) in darksong.exe: 0x000006D9: There are no more endpoints available from the endpoint mapper.

The "access is denied" error makes me think there is some issue opening the file itself, although if I purposely enter an invalid filename it's a completely different error which crashes, so I know it's finding the file but perhaps is having some issue actually accessing it?
Also, even if I exclude the "InstallCommandDefinitionsFromStorageFileAsync()" line The exceptions are all still thrown.
Any help is appreciated, thanks in advance!
You have certainly an error in your xml file (if you have set for exemple in command an item using PhraseList but you have forgot the PhraseList node in your xml)
i was actual trying this tutorial: http://wso2.com/library/tutorials/2012/12/providing-xacml-fine-grained-authorization-webapps/
on the authentication with admin:admin on localhost:9763/Entitlement_Sample_WebApp/protected.jsp i encountered an error:
exception
org.wso2.carbon.identity.entitlement.filter.exception.EntitlementFilterException: Exception while making the decision : java.lang.NullPointerException
org.wso2.carbon.identity.entitlement.filter.EntitlementFilter.doFilter(EntitlementFilter.java:191)
My WSO2 IS PDP receives the request and responds also correctly with a XACML Response : Permit
so where could be the problem ??
thank you
The problem caused by an error of EntitlementFilter, so I could solve this by correcting the source file EntitlementFilter.java (line 191)
like below:
simpleDecision = decisionElement.getFirstChildWithName(new QName("Result")).getFirstChildWithName(new QName("Decision")).getText();
rewrite it:
simpleDecision = decisionElement.getFirstChildWithName(new QName(“urn:oasis:names:tc:xacml:3.0:core:schema:wd-17″,”Result”)).
getFirstChildWithName(new QName(“urn:oasis:names:tc:xacml:3.0:core:schema:wd-17″,”Decision”)).getText();
It ommitted namespace in QName method
The detail is here (https://nparkstar.wordpress.com/2015/01/27/wso2-as-sample-authorization-%EC%98%A4%EB%A5%98-%EC%88%98%EC%A0%95/).
Sorry, it is written in Korean, but I wish it could helpful.
It could be anywhere starting from this line : pepProxy.getDecision(userName, resource, action, env)
It could be in your pepProxy code, where they are getting back the result, or might be in the other lines after this call in that try catch.
One thing is sure PDP is not at all culprit.
Please paste your full exception here if you want to know precise problem + Solution.
