Azure Functions not Found

Question

Azure Functions not Found

TheNerd-0042 50

Hi Everyone,

I am trying to understand why am unable to see the function which I created under a Function App. For example: I have created a Function which uses Python with Linux OS and a new Storage Account to get some messages from EventHub and alter the names of some columns and send it to Azure Service Bus.

Things I did:

- Created an EventHub Trigger for the function by pointing it to the eventhub where I want to import the chagned data (JSON format)

- Added Azure Service Bus Topic Name and Primary Connnection String under Environment Variables

- Added requirements.txt as it has libraries pre-requisite for the below python script to work

- Added the Python Script to do the job and I saved the .py file as well.

Now when I just come out of the function andthen go to the Home Page of Function App, I am unable to see my newly created function at all, its just disappeared. Its showing nothing and asking me to create a new function again.

But still I am to see all the files which created under App files of the Function App? How?

Why does this happen? Anyone can help me here or explain please?

Best Regards

Hi @TheNerd-0042,
To ensure your Azure Function is working correctly, first verify that it was successfully deployed saving code isn’t enough, as deployments can sometimes fail. You can check the deployment logs in the Azure portal for any errors. Make sure your Function App is properly configured for Python, including the correct Python version and environment settings matching your development setup.

Also, confirm that the folder structure is correct, with each function in its own folder and containing a function.json file. Check for any access restrictions or visibility settings that might be hiding your functions in the portal. Ensure all necessary app settings, such as connection strings and environment variables for Event Hub or Service Bus, are properly set. Finally, try running your function locally using Azure Functions Core Tools to confirm it works outside the portal.

I hope this helps resolve your issue. Feel free to reach out if you have further concerns.

Hi @Ranashekar Guda thank you for your answer. But I can confirm that I have configured the function app correctly and the deployment was also successful, there is no option to hide or restrict the visibility of the function so, yeah do you have any other solutions?

Hello @TheNerd-0042,
Since your deployment was successful and files are visible under "App files" but the function isn’t showing in the portal, it’s likely due to a missing or incorrect function.json file. Each function must be in its own folder with a valid function.json to be recognized by the Azure Functions runtime.

Also, ensure the folder structure is correct, host.json is present at the root, and the Python version matches your Function App settings. Try restarting the Function App to refresh the runtime. If the issue continues, redeploying using Azure CLI or VS Code can help ensure the structure is clean. Hope this helps. Do let us know if you any further queries.
