Azure function python v2 with external packages HTTP Trigger not visible in Azure Portal after deployment

Refer this SO Thread and my answer - https://stackoverflow.com/questions/76458717/why-is-the-functions-runtime-not-finding-my-functions-when-i-import-certain-pack/76463210?noredirect=1#> The Azure python Function with V2 programming model including external packages and imports in function_app.py works locally, But when I deploy it in Azure the Function Trigger is not visible. If I deploy default HTTP Trigger with python v2 programming model, The trigger is visible after deployment. But not when i add custom imports in the function_app.py and requirements.txt. Refer this image - https://i.imgur.com/CjCnsY8.png but the function files are visible in app files like here- https://i.imgur.com/R3SZWcW.png . I tried the deployment with App service plan and consumption plan both, Still no luck. I also added AzureWebJobsFeatureFlags:EnableWorkerIndexing settings, I also tried to deploy this function as zip using azure cli zip command with required settings to deploy function as zip, I also tried to deploy it with function core tools func azure functionapp publish command and also via VS code still no luck.
