I am perplexed,from a weird error which i have no idea as i am new to celery, this error occurs on just the setup phase, every thing is simply configured as written in the celery doc https://docs.celeryq.dev/en/stable/django/first-steps-with-django.html the tracback is:

(env) muhammad@huzaifa:~/Desktop/practice/app$ celery -A app worker -l INFO

the init file is:

from __future__ import absolute_import, unicode_literals

from .celery import app as celery_app

__all__ = ('celery_app',)


celery.py:

import os

from celery import Celery

# Set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'app.settings')

app = Celery('app', broker='localhost')

# Using a string here means the worker doesn't have to serialize
# the configuration object to child processes.
# - namespace='CELERY' means all celery-related configuration keys
# should have a `CELERY_` prefix.
app.config_from_object('django.conf:settings', namespace='CELERY')

# Load task modules from all registered Django apps.
app.autodiscover_tasks()


@app.task(bind=True)
def debug_task(self):
print(f'Request: {self.request!r}')
