My azure function works well locally and gives response 200 ok, however, although the remote deployment is successful, it throws response 500

I have been successful in testing my azure function locally. But whenver i try to test it remotely it fails with response 500 error. There is no problem with deployment as the deployment was termed successful.

I have looked into this issue, and tried to solve the problem. However, it seems that my local.settings.json and application settings are fine. Here is the snap shot of both.

My local.settings.json

I also checked into to my Application Insights > Logs and ran the query for exceptions causing failures as below.

I found out that the exceptionType thrown was "Microsoft.Azure.WebJobs.Script.Workers.Rpc.RpcException" with failedMethod of "System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw". I investigated on this exception but was unable to find the root cause of my error.

I would highly appreciate if any prodigies in this field could help me out and resolve this issue. Thank you.

@Lakpa D. Tamang Thank you for reaching out to Microsoft Q&A. From the statement above, it was pretty clear that the issue occurred when deployed in Azure (not locally) and you already had validated application setting.

Based on the exception Microsoft.Azure.WebJobs.Script.Workers.Rpc.RpcException above and the scenario, it matches issue #787 described in python GH repo. There was a good suggestion to use Live Metrics to get live stream log and please check requirements.txt as described in the comments section which resolved the issue.

If you still face the issue, please share code snippet, requirements.txt, runtime version etc. that help in reproducing the issue. I hope this helps with your question and let me know if you have any other questions.
