Celery doesn't find the module storefront

Hey Mosh,
I followed your ultimate django course. It was going very well. Until I got stuck on the running the background task module. I have followed your instructions regarding Celery. But whenever I run the command to start celery worker, it shows the following error:

Usage: celery [OPTIONS] COMMAND [ARGS]...
Try 'celery --help' for help.

Error: Invalid value for '-A' / '--app':
Unable to load celery application.
The module storefront was not found.

I tried googling the problem but it was in vain. I’m using Django version 4.2 and Celery 5.4.
