(remote rejected) master -> master (pre-receive hook declined)

I'm having problems pushing to Heroku. This is happening on my first "Git push Heroku Master." I'm using Node JS.

The error I am getting is as follows:

remote:  !     Push rejected, failed to compile Node.js app.
remote: 
remote:  !     Push failed
remote: Verifying deploy....
remote: 
remote: !       Push rejected to fathomless-wave-74799.
remote: 
To https://git.heroku.com/fathomless-wave-74799.git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/fathomless-wave-74799.git'

The error first starts with this:

remote:        stream.js:74
remote:        throw er; // Unhandled stream error in pipe.
remote:        ^
remote:        
remote:        Error: invalid tar file

I'm a bit new to Heroku so any help is greatly appreciated.
