Answer 3

did you read the Getting Started with Node.js on Heroku article on Heroku Dev Center?

You need to declare your process type with Procfile. To do so, create a file named Procfile, with the following content:

assume that your javascript file is called web.js.

p.s. don't forget to add the Procfile to git and commit it.

For me, doing npm init was enough

Answer 5

I have encountered this issue a few time before and it was because I was trying to push a remote branch to heroku.

To solve the problem, instead of using:

git push heroku master

I used:

git push heroku my-branch:master

This pushes the remote branch my-branch in the git repository to the master branch of heroku.
