I was getting started on deploying Django applications on DigitalOcean, following this tutorial. So, I completed step-4 but could not see that “it works” spacecraft thing, instead, I got an ModuleNotFoundError, no module named masons_django_app

In my settings.py I have ROOT_URLCONF = 'masons_django_app.urls' & WSGI_APPLICATION = 'masons_django_app.wsgi.application' that I think are related to this problem

Please help!
