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         


        

Answer 1

I was getting the same problem, and tried everything posted here. I was getting:

Procfile declares types -> (none)

Instead of Procfile declares types -> web. My fix was to change in the regedit to 0 (tutorial here https://www.thewindowsclub.com/show-file-extensions-in-windows) and then deleting the .txt in the end of Procfile (So It was just a file with no extension). After that my problem was solved! You can check if you have solved doing the following commands in the cmd:

heroku ps 

Should display something like:

=== web (Free): gunicorn app:app (1)

Or the git push:

git push heroku master

And that should display:

Procfile declares types -> web
