A strange thing happened to me today lol

I tried to log on to check my credits and I received the following…

Status Code: 404; Not Found

Sorry for the inconvenience Mark. Looks like I need to fix something there, I am investigating.

To clarify: In the case I am seeing here, the 404 error appears on login, with an URL like this in the browser address bar:
https://manage.botengine.org/login/fromauth0?code=12345678

It turns out there was a problem with a software component from Microsoft which caused this problem to sporadically appear.

Microsoft provided a fix and I configured the website accordingly.
I did not see the error since.
@Mark, how does it look on your end?

Engineering details:
Application insights showed an 404 error was returned for requests after an InvalidProgramException was thrown. In our case the stack reached into cosmos db aka document db retry code:

I changed the application insights configuration for the azure web app to switch to the Preinstalled Site Extension model as recommended at https://github.com/dotnet/coreclr/issues/18323#issuecomment-439971479

Lesson learned: If you want to use instrumentation like this, keep the code mapping within the build pipeline (to avoid surprises at runtime) unless you can come up with a good reason not to.

It’s working good now. Thank you for looking into it for me.
