Issue while deploying my Django app - ModuleNotFoundError: No module named 'level'

1

Hello,

I have a Django app with a PostgreSQL, I am currently hosting the database somewhere else and I’ve decided to deploy the Django app to Render.com. I installed gunicorn and uvicorn and used whitenoise to server staticfiles. I also added all necessary environment variables and the building goes fine without any errors, however I get the ModuleNotFoundError: No module named ‘level’ error, level is an app inside my project and it is perfectly added to the INSTALLED_APPS list and it works fine on my machine.

Here is the full error:

Here is my INSTALLED_APPS:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    "whitenoise.runserver_nostatic",
    'django_browser_reload',
    'django_recaptcha',
    'adminsortable2',
    'django_email_verification',
    'level',
    'player',
    'region',
    'levelrecord',
    'recordsubmission',
]

And my project looks like this:

From what we can see, it does look correct. One tricky item that can crop up is a difference in casing between your local copy and the repo as uploaded (e.g. to GitHub). Have you confirmed that your levels directory has exactly that casing in both locations?

Oh my God. Just checked my repository and the apps are all in capital, I’ve changed that to a lowercase app name in the early phases of development but I didn’t know GitHub didn’t actually modify that. Much appreciated!
