Heroku: No such process type worker defined in Procfile

Question

I'm trying to resize workers but the following message appears:

MacBook-Pro-de-Ricardo:subastas ricardo$ heroku ps:resize worker=2X
Resizing and restarting the specified dynos... failed
 !    No such process type worker defined in Procfile.

this is my procfile:

web: gunicorn -k flask_sockets.worker chat:app

Unicorn workers and Heroku workers are not the same. Unicorn workers are in your web process, responding to requests.

• https://devcenter.heroku.com/articles/python-gunicorn

Heroku workers are background workers.

If you need more ram et. al. for your workers, you just need to re-size the web type:

• https://devcenter.heroku.com/articles/dyno-size

ex:

$ heroku ps:scale web=n:2X

That reads: "scale to n web worker(s) at 2X dyno size", where n is the number of web dynos you want running.
