Unable to start Celery in Flask application - python-3.x

Question

I am getting the following error when trying to start a Celery worker (Windows).
I'm using Celery 5.0.5.
celery.exe -A api.app -> ModuleNotFoundError: No module named 'api'
main.py
import os
from api.app import create_app
app = create_app(os.getenv("FLASK_ENV"))
if __name__ == '__main__':
app.run(threaded=True, host='0.0.0.0')
api\app.py
from celery import Celery
from flask import Flask
from flask_redis import FlaskRedis
from flask_restful import Api
from api.config import env_config
redis_client = FlaskRedis()
celery = Celery(__name__, broker="redis://...")
def create_app(config_name):
import resources
app = Flask(__name__)
app.config.from_object(env_config[config_name])
redis_client.init_app(app)
app.config.update(
CELERY_BROKER_URL="redis://...",
CELERY_RESULT_BACKEND="redis://..."
)
celery.conf.update(app.config)
with app.app_context():
from .routes import ccl_routes
from .routes import scan_routes
return app
Folder structure is like so:
helheim
| |api
| |app.py
| |__init.py__
|main.py
What am I doing wrong? It's late here so probably something obvious but can't see it :)
Thanks!

edit: i think u can try celery -A api.app.celery worker before doing any major changes.
not sure how your entire file structure looks like but for example
project
| |_api
| |_app
_...
you should start it with celery -A project.api.app.celery worker. replace .celery to your celery instance name. or you can also refer to this repo https://github.com/mushcatshiro/flask-template.
also note, its a bit challenging to work with celery 4.X on windows from my experience, use celery 5.0 instead.
