What is the reason for “Procfile declares types -> (none)” in Heroku?

Question

I am trying to deploy a test app to Heroku --stack cedar but every time I do my Procfile is being ignored.

It should be saying this:

Procfile declare

Make sure you don't give any extension to Procfile. I did and got similar error. Also check syntax. For e.g:

web : sh setup.sh should be

web: sh setup.sh
