Is there a AAD login web test that I can use for the Azure availability test as the one I am using is randomly generating context parameter errors?

Question

We are running a web test that uses AAD to login to a web site. When run via Visual Studio the web test runs correctly. However, when run in Azure availability this generates missing context parameter errors. I have attached the error call stack. This is causing availability dips. The error is not specific to a Azure region. I need a web test that works.

There is no try catch mechanism in web tests so I cannot filter out such errors.

I can't upload or paste the web test but its a Azure AAD login web test.

I expect the web test to work. However, I get the following errors:
