unable to retrieve function in Azure Function APP

Question

The problem "internal host error" appears every time I attempt to build a function (HTTP Trigger) in a Function APP. However, after several attempts, I was able to successfully create the function. After writing the function and testing, I exit the page, but upon returning to the same function, I continually receive the message "error retrieving the function." Eventually, I am unable to locate the function at all because it has been automatically deleted.

Hello Jawher Khalifa,

Thanks for your question.

I will recommend you set up application insights telemetry

https://learn.microsoft.com/en-us/azure/azure-monitor/app/opentelemetry-enable?tabs=python

It will show you errors in the app insights exception panel

Please check Functions metrics for the HTTP Server Errors at the time of the issue.

You can use the diagnostic steps here:

I had this issue. So I chose to delete the whole function app and create a new.

I was creating the functions inside Azure. Now, in my new function app, only VS Code Desktop, and Other editors or CLI is enabled, not the option to create it on the azure site. so I cannot even do what I was doing before.

The problem could be related to using existing resource group. Recommended is to always create a new resource group for new function apps

Nevertheless, the only way I could get past the problem was to learn to do it from VS Code.
