Problem when running celery with Flask. What is the problem?

Question

Python

My flask app:

from flask import Flask
from celery import Celery


app = Flask(__name__)
app.debug = True
app.config['CELERY_BROKER_URL'] = 'mongodb://логин:пароль@ds243041.mlab.com:43041/flaskmongodb'
app.config['CELERY_RESULT_BACKEND'] = 'mongodb://логин:пароль@ds243041.mlab.com:43041/flaskmongodb'

celery = Celery(app.name, broker=app.config['CELERY_BROKER_URL'])
celery.conf.update(app.config

@app.route('/run_Task')
def run_celery_task():
    my_task.delay()
    return 'Задача запущена'


@celery.task(name='app.my_task')
def my_task():
    return 'task completed'

if __name__ == '__main__':
    app.run()

In the console, I write
celery -A run_flask.celery worker --loglevel=info
And the output is an error:

celery.exceptions.ImproperlyConfigured:
Cannot mix new setting names with old setting names, please
rename the following settings to use the old format:
include -> CELERY_INCLUDE
Or change all of the settings to use the new format :)

Answer 1

Cannot mix new setting names with old setting name...
in Celery, the format has changed, you need all the parameters to be called either in the old or in the new way

Answer 2

celery.conf.update(app.config- parenthesis missing?
