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

Project/
  GroomingService/
    accountApp/
    adminApp/
    appointmentApp/
    GroomingService/
      __pycache__
      _init_.py

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
import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'GroomingService.GroomingService.settings')
application = get_wsgi_application()

How can I direct it to find the modules?

CodePudding user response：

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

CodePudding user response：

Well it gave me a different error but its a start,

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
