unable to retrieve function in Azure Function APP

Question

unable to retrieve function in Azure Function APP

Jawher Khalifa 40

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.

Hi!
I have the same problem. The first time I created a function (used python) and even tested it (worked well) but after saving and trying to see it from a list - I don't see nothing.
If I refresh original function page - Error while loading
When I try to create a new function in the same app I've got Error while loading once more**.**
Then later in Azure portal, only two other options left (no in web).

I tried to restart the app, this didn't help.
I tried to create new app and test there - the same.

Then I tried to create from local env, did as it was in tutorial, locally function worked, also deployment was successful:
func azure functionapp publish testPGAppInsights1 --python --force
Deployment successful. deployer = Push-Deployer deploymentPath = Functions App ZipDeploy. Extract zip. Remote build. Remote build succeeded!

then
az functionapp function list -g lab -n testPGAppInsights1
[]

nothing showed and in the web I don't see nothing too.

Please, help.

Facing the exact same issue as @Abiola Akinbade , its really strange issue. I create a function in the Azure portal and it was working well and I could see all the invocations. But suddenly it was deleted by itself. After that I couldnt add any new functions and continuously got "Error retrieving function error". I even deleted and created a new function app, after which I was able to work by creating new function. But again the same issue occurred.

Same exact issue. This is incredibly annoying and frustrating. Thinking about writing Azure off entirely, as I constantly run into issues at every turn.

I am having same issue as mentioned by @Abiola Akinbade , @Karthik Ramnath and Cody. I created azure function app and function in azure portal and it was working fine and suddenly it disappeared. I tried logout and login to make sure it's not a session issue. This happened twice, last time I deleted the function app and created again. But again it got deleted and not able to create any function as @Karthik Ramnath mentioned. It is really frustrating.

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:
https://learn.microsoft.com/en-us/azure/azure-functions/functions-diagnostics#start-azure-functions-diagnostics

You can mark it 'Accept Answer' and 'Upvote' if this helped you

Regards,

Abiola

This does not solve the issue. Why are my functions getting lost and then I keep receiving this error? This is basic stuff that AWS Lambda has no issue with. Please fix ASAP!!

Answer 2

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.
