I'm trying to deploy a simple python bot on Heroku but I get the error
couldn't find that process type 
When I try to scale the dynos. I already made a procfile and it looks like this:
web: gunicorn dep:app, where "dep" is the name of my python code  
What could be the reason?
Make Sure Procfile should not have any extension like .txt
otherwise this will be the error
remote: -----> Discovering process types
 remote:        Procfile declares types -> (none)
To create file without extension type following in cmd 
 notepad Procfile.

Now add web: gunicorn dep:app and save
Now when you will git push heroku master the above lines will be like
remote: -----> Discovering process types
 remote:        Procfile declares types -> web
And the error is gone when you will run
C:\Users\Super-Singh\PycharmProjects\URLShortener>heroku ps:scale web=1
Scaling dynos... done, now running web at 1:Free
Couldn't find that process type, Heroku
