Azure Function run correctly in local machine but when deployed to Azure function App it is not showing up in overview section

I wanted to deploy CRON Timer Trigger using Azure Function in Python. I tried to deploy it using VS Code and through command as well func azure functionapp publish <functionapp_name> But in both cases trigger is not showing azure portal.

Here are the steps I followed:

Step 1: Installed all the following prerequisites:

Installed Azure Core Tools v4 Have Azurite V3 Extension Installed. Working in Python 3.11.8. Latest version of VS Code in Windows Azure Function Extension installed

Step 2: Created Azure Python Function with Consumption Plan

Step 3: Created a Function App with Python v2 Model

Used VS Code Azure Extension to create Function locally

Step 4: After doing required changes in default function code, I tried to deploy that using VS Code Azure Extension by selecting the required function app: Deployed using following Azure Extension

Step 5: Checked for deployment status. In VS Code it is shown as successful. In Portal all files which are not ignored, are uploaded to the Azure Function Resource but it's not showing as a function.

Function is not showing up in overview

However I can see files successfully deployed in App File Section

Step 6: Also I have checked deployed Azure Function in VS Code but I can't see function.json under Function.

Cross checked in VS Code

My function_app.py looks like the following:

Code is working fine when tested locally but when it is published it is not showing in azure portal. image

Any help or suggestions will be appreciated as I want to test the deployment reliably.

I tried all the above-mentioned steps. The expected results is successful deployment of Azure Function.

I'm having some of the same issues. I'm running on node and found that the latest tag isn't working for me (4.33.2). I did this and it worked.

FROM mcr.microsoft.com/azure-functions/node:4.33.1

Can you try something similar? Drop back one version?
