In fact, after I followed all the steps exactly as mentionned by JohnnyB, when I want to start the app in Heroku I get this erro , (I am using the free way, without a credit card )
Application error
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail
