I am deploying my django app+telegram bot to heroku. While migrating data to heroku, i am getting an error:

C:UsersAcerbrand_onlinebrand_online>heroku run python manage.py migrate --app brand-telegram
Running python manage.py migrate on ⬢ brand-telegram... up, run.7513 (Basic)
python: can't open file '/app/manage.py': [Errno 2] No such file or directory

everything seems simple, but i am not writing /app/ before manage.py.
I dont know where did it come from.

Procfile:

web: gunicorn brand_online.wsgi
worker: python main.py

How to fix?

heroku run python C:UsersAcerbrand_onlinebrand_onlinemanage.py migrate

i tried to use detailed link to manage.py
