When I try to access my app after deployment it results in an H10 error. It seems to reference favicon in the log and also says that Django isn't installed (I have run pip3 list in my venv and it appears to be there, it is also in requirements.txt).
Here is the log:

Here is the contents of my Procfile:

After updating requirements.txt I get this issue:

Your Procfile is not a valid one
You have to change
web: python manage.py runserver 0.0.0.0:$PORT
to
web: gunicorn your_django_progect_name.wsgi:application --log-file - --log-level debug
Be sure to add gunicorn to your requirements.txt file as well. read this
