Couldn't find that process type, Heroku
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
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?
