Deploying Django Web App using Devops CI/CD onto Azure App Service

I'm trying to deploy simple django web ap to Azure App Service using CI/CD pipeline (the most basic one that is offered by Microsoft for app deployment- no changes from me). However I'm getting the following error:

2021-03-08T16:55:51.172914117Z   File "", line 219, in _call_with_frames_removed
2021-03-08T16:55:51.172918317Z   File "/home/site/wwwroot/deytabank_auth/wsgi.py", line 13, in 
2021-03-08T16:55:51.172923117Z     from django.core.wsgi import get_wsgi_application
2021-03-08T16:55:51.172927017Z ModuleNotFoundError: No module named 'django'

I checked other threads and tried doing all the things mentioned but it did not help, or I am missing something:

In wsgi.py I added:

import os
import sys

sys.path.append(os.path.dirname(os.path.abspath(__file__)) + '/..' )
sys.path.append(os.path.dirname(os.path.abspath(__file__)) + '/../licenses_api')
sys.path.append(os.path.dirname(os.path.abspath(__file__)) + '/../deytabank_auth')

from django.core.wsgi import get_wsgi_application


os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'deytabank_auth.settings')

application = get_wsgi_application()

But still getting the same error, where django is not recognized. I can see that reuqirements.txt is being installed successfully and it has all the neccessary libraries there (including Django)

My CI/CD yaml file looks like this:

# Python to Linux Web App on Azure

Maybe I need to configure something in the Azure App Service? But i am not sure exactly what.
