django celery error: Unrecoverable error: AttributeError("'EntryPoint' object has no attribute 'module_name'")

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
[2022-04-04 16:21:40,988: WARNING/MainProcess] No hostname was supplied. Reverting to default 'localhost'

During handling of the above exception, another exception occurred:

AttributeError: 'EntryPoint' object has no attribute 'module_name'

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}')

For your information, rabbitmq-server is running on localhost thats why i have set BROKER_URL TO ‘localhost’

 rabbitmq-server.service - RabbitMQ Messaging Server
     Loaded: loaded (/lib/systemd/system/rabbitmq-server.service; enabled; vendor preset: enabled)
     Active: active (running) since Sun 2022-04-03 16:14:04 PKT; 24h ago
   Main PID: 1005 (beam.smp)
     Status: "Initialized"
      Tasks: 91 (limit: 9090)

idk why this is happening, i have been look around for like hours and cant find a solution and not even the error on google or anywhere.
any help would be greatly appreciated
Thanks!
