Functions in Function App Not Showing and Dissappeared For Unknown Reason

Ardel Vito Putra Herijanto 20

Hi, so im using azure function app and integrate it to IoT Hub and at the beginning actually it works fine but somehow after some error code in my function app logs in monitor tab it turns out the functions in my azure function app dissappear randomly and when i open that function it keeps loading.

My issue is similar like this one https://developercommunity.microsoft.com/t/Azure-Function-App-Dissappeared-randomly/10639110 but the solution is not clear enough.

Thanks in advance for any helps or discussions

Hello @Ardel Vito Putra Herijanto

Thanks for reaching out in the Microsoft Q&A!

To troubleshoot your disappearing Azure Function App functions, first, analyze any error codes you encountered. Ensure your code isn't overly synchronous, which can overload the runtime. Check for the presence and correctness of the function.json file. Try restarting the function app and validate application settings for typos and compatibility. If needed, temporarily disable worker indexing. Verify connection string accuracy. If issues persist, consider opening a support ticket with Microsoft Azure.

If you found this solution helpful, don't forget to upvote and accept as answer. Thank you!

Hi, thank you for your response. Unfortunately i can't access my function since it keeps loading and it already dissappear, this is my screenshot that i take last night. I can't check more details about the function.json but for the latest error message in my code before my function is dissappeared is Exception while executing function: Functions.spmfunction Result: Failure Exception: NameError: name 'IoTHubRegistryManager' is not defined Stack: it little bit strange since actually i already adding from azure.iot.hub import IoTHubRegistryManager based on tutorials in here

And when i tried to add new function on my function app it always showing an error like this, do you have any suggestions ?
