When I try to deploy a python function app I get the following error. The issue is specific to python app deployment only, deploying .net core apps work fine.

    @Raghul Kannan Thanks for your cooperation and patience on this. Upon troubleshooting we understood that the issue with the "FUNCTIONS_WORKER_RUNTIME" because of this function host went unreachable. Suggested the below cmdlet to pin the function worker runtime to Python|3.8 and it fixed the customer issue.

    az functionapp config set --name <FUNCTION_APP> --resource-group <RESOURCE_GROUP> --linux-fx-version "PYTHON|3.8"  
    

    Feel free to reach back to me if you have any questions on this,
