I am new to heroku and express.js. I try to go through the tutorial, but I cannot make it with the step 'git push heroku master'. I followed the tutorial exactly. Below is the error message:

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:
web: node web.js
assume that your javascript file is called web.js.
p.s. don't forget to add the Procfile to git and commit it.
You need a package.json file (and a Procfile), it is likely not the case.
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.
Just for the record, I had the same problem and it turned out to be one of the Config Vars in Heroku. I remove the config vars and the app was pushed successfully.
