the two most notable things I could find from this error list were
2022-05-18T01:09:37.493821+00:00 app[web.1]: ModuleNotFoundError: No module named 'appointmentApp'
and
2022-05-18T01:09:37.554411+00:00 app[web.1]: gunicorn.errors.HaltServer: <HaltServer 'Worker failed to boot.' 3>
I know that with error H10 there might be something wrong with my procfile
web: gunicorn GroomingService.GroomingService.wsgi
My project file struture

Earlier I was also having trouble because it was telling me that
wsgi could not found
No module named 'GroomingService.wsgi'
and then that settings could not be found
Because of that I added an extra GroomingService to the file path so that it could find it in both my Procfile and my wsgifile
#wsgi.py

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

How can I direct it to find the modules?

Answer 1

I had to back track, if someone else runs into this, you might be having the same issue
Basically this
Couldn't find WSGI module deploying Heroku
The file structure is wrong manage.py has to be at the root of the project, where Procfile and requirements.txt are, but if that's not possible to change then you can change the proc file
old procfile
web: gunicorn GroomingService.GroomingService.wsgi
new procfile
web: gunicorn --pythonpath GroomingService GroomingService.wsgi

Answer 2

Check your settings.py file, you might have not registered that app in your INSTALLED_APPS section.
