Hi,

I've seen this issue quite a lot with customers using Python Functions. In my opinion it's a bit of a bug in Azure that doesn't show a failing dependency, module/library, etc in the logs. However, here is the main GitHub issue on this problem:

https://github.com/Azure/azure-functions-python-worker/issues/1262

Specifically, review the comments which have a lot of troubleshooting tips/fixes for various different problems faced.

Sometimes it's the order in which the function imports or requirements.txt issues on library versions etc.

Review the GitHub issue comments which have a lot of fixes and pointers which will guide you to sort this issue.

Additionally, you can in Azure go to 'Resource health' on the Azure Function > 'Diagnose and solve problems' button at the top which will take you to the 'Function App Diagnostics (Preview)' where you can click on 'Availability and Performance' and review on the left the Python Function or Startup checks to verify any issues which sometimes help to identify some problems. But I suspect the GitHub page will be infinitely more useful for you.

If this was useful and helped you please feel free to mark as the accepted answer.

@Komre, Ved Prakash Thanks for reaching out. You can review the application insights logs to know if there was any error/exception in the azure function runtime or while executing your function. In case if there is no error/exception then it could be function sync issue and you can try syncing the function app again and see if it helps you.

You can also review the diagnose and solve blade on your function app to know more details on the issue and the action plan if any to resolve the issue.
