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 had this error and tried all the solutions above but they did not work. Turns out that I had created the git repository in the root of the virtual environment. Which seems reckless but hey...

So if you have tried all the solutions and they don't work check where you created your repository and make sure it is in the root of your project source code and not anywhere else.
