I'm new to coding in Python so bear with my errors. I keep encountering this error even when I haven't added anything into the code yet.

Note: I did migrations and makemigrations just in case but I still get the same error.

I am currently going through 'The Definitive Guide to Celery and Django' course by testdriven.io. I've managed to containerize the whole application. Everything was built correctly and seemed to work just fine, but when I tried to enter the Django shell and run a task, to ensure everything works correctly, the following error appeared.
>>> divide.delay(1, 2)

I've done a quick research and in most cases it seemed to be a lack of the following lines
from config.celery import app as celery_app
__all__ = ['celery_app']
in the config.__init__.py, but it's clearly not an issue here.
I also double checked whether redis container is up and listening on port 6379.
The only difference between my code and the course code is that I decided to use Poetry package manager instead of requirements.txt file and pip.
At this point I am a little bit confused I'll be thankful for any tip. You can find the whole code below:

The main issue was that I was trying to run rqworker files instead of python manage.py rqworker files
Just created a project, added app definition in settings.py, and created an app with a urls.py file seperately and tried to include the urls.py file in the main urls.py file that is created by default when we create a project and tried to return a HttpResponse in a seprate file.

I believe the error message is pretty clear:
The included URLconf <module 'hello.urls' from 'C:\Users\Sujit\Documents\CS50\lecture3\hello\urls.py'> does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.
Make sure this file contains a variable named urlpatterns, and that you can succesfully import it.

Any help would be helpful
CsrfResponseMiddleware was removed in Django 1.4. You're probably running Django 1.2-1.3 in one environment and Django 1.4-master in the other.
