The Procfile is defined as below:

web: gunicorn app:app --workers 1 --worker-class=gevent --bind 0.0.0.0:$PORT --timeout 600

and the logs from Heroku are:

2022-03-10T09:04:35.223306+00:00 heroku[router]: at=error code=H14 desc="No web processes running" method=GET path="/" host=emotion-sys.herokuapp.com request_id=0f9c469f-1bdb-422c-8bc7-62396368bc40 fwd="103.75.160.161" dyno= connect= service= status=503 bytes= protocol=https
