Can you change your listener to something like this because I guess heroku doesn't allow you to assign listening ports but provides them dynamically. In your case 3000 || process.env.PORT it always return PORT 3000.

app.listen(process.env.PORT || 3000, function() {
    console.log("server started");
});
