I'm using django with celery, celery beat, and redis to run periodic tasks.
The problem I'm having is that tasks registered in celery are received but not executed.
Also, the task stops in the middle even though I have not specified a stop setting.
The environment is as follows.
windows10
python = 3.7.9
PostgreSQL 13.3
Redis server v=3.0.504 sha=00000000:0 malloc=jemalloc-3.6.0 bits=64 build=a4f7a6e86f2d60b3
[requirements]
celery==5.0.5
Django==3.2.4
django-celery-beat==2.2.0
django-celery-results==2.0.1
django-redis==5.0.0
redis==3.5.3
I built the environment by referring to the following site.
https://docs.celeryproject.org/en/stable/django/first-steps-with-django.html

| +-__init__.py
| +-tasks.py

settings are configured as follows.

from celery import Celery
# set the default Django settings module for the 'celery' program.
os.environ.setdefault('DJANGO_SETTINGS_MODULE',
'Project.settings')
app = Celery('Project')
# 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 registere
app.autodiscover_tasks()
@app.task(bind=True)
def debug_task(self):
print(f'Request: {self.request!r}')
project/project/init.py
# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from celery import app as celery_app
__all__ = ('celery_app',)
project/app/tasks.py
from celery import shared_task
@shared_task
def hello():
print("hello")
project/app/init.py this is empty
(1) What we did
In the browser, in the admin settings, set the hello() task to run once every 5 seconds permanently.
(2) What I did
Running the redis server at the command prompt: redis-server
In this environment, use PowerShell to run the following command in the project root location to run the celery worker
celery -A StreamerMonitoringWebsite worker -l info
Also, run the following command in another Powershell to run celery beat
celery -A StreamerMonitoringWebsite beat --scheduler django_celery_beat.schedulers:DatabaseScheduler
(Result)
redis and celery beat were still running and did not output any logs.
No logs were left in the results of the administration site either.
The celery worker output the following logs.

Where and how do I rewrite it so that it can be run as a recurring task?
If you need more information than these to solve my problem, please let me know which information you want.
【Addendum】
When I dared to register a misspelled task in beat, I got a failed result in the administration screen.
Also, if you run beat with "--loglevel=INFO", you will see that tasks are being sent at the specified frequency.
On the other hand, the worker recived the deleted task as if it were cached.
