Node.app - runs locally, deploys correctly but fails to work

i'm trying to deploy my node app on heroku.

This app works fine localy, and is properly pushed on heroku.

However, whenever I try to reach the URL, the browsers displays:

An error occurred in the application and your page could not be served. Please try again       in a few moments.
If you are the application owner, check your logs for details

At first, I thought that was because I didn't pay attention the port I was listening to (I don't really understand how Heroku processes and if the port is important) so I copied the same code as they did in their Getting started...:

    port = process.env.PORT || 5000;

server.listen(port, function() {
console.log("Listening on " + port);
});

my package.json is very basic : 

   {

"name":"Radiorev",
"version":"0.0.1",
"dependencies":{

    "express":"3.3.5",
    "socket.io":"0.9.16"
}
  }

Help!

By the way when I type heroku log, my cmd tools displays something quite unreadable... with zero line breaks.

The problem might be that you scaled your web dynos to 0, so there's no one to run the server. Try running:

heroku ps:scale web=1

Heroku does not support websockets, so try turning it off

// assuming io is the Socket.IO server object
io.configure(function () { 
  io.set("transports", ["xhr-polling"]); 
  io.set("polling duration", 10); 
});

as per Using Socket.IO with Node.js on Heroku

update: H14 - is Error H14 (No web processes running)

try adding Procfile with following contents:

web: node server.js
