Answer 1

try updating your Procfile to read as:

web: gunicorn grad.wsgi --log-file - --log-level debug --preload --workers 1

Answer 2

You correctly identified that the key line in the error message is the ModuleNotFoundError.

The problem is that your Django project directory (the one containing manage.py) isn't in the project root, it's in the gpproject directory.

Therefore you need to add that directory to the Python path with the --python flag, so that the grad module inside it can be imported.

web: gunicorn grad.wsgi:application --python gpproject --log-file - --log-level debug --preload --workers 1
