I have my first node.js app (runs fine locally) - but I am unable to deploy it via heroku (first time w/ heroku as well). The code is below. SO doesn\'t let me write so much
If, like me, you're configuring Heroku to run a script from your package.json file on deploy, make sure you haven't hard-coded the value of PORT in that script! If you do, you'll end up like me and spend an hour trying to figure out why you're getting this error.
