Port 34037 is already in use Heroku + Nodejs + Express + WebSockets - node.js

Question

I tried everything I could find, but I can't get my deployment to work. I keep getting 'Application Error', although the app runs on my http://localserver:5000
Seems the problem is in bin/www
Here is the error log i get in Heroku. I suppose the issue is "Port 34037 is already in use"

I am following the Heroku docs to deploy websockets with ws module.
Here is part of my app.js Nore the part var port = process.env.PORT || 5000
**var express = require('express')
var http = require("http");
var Crawler = require("simplecrawler");
var cheerio = require('cheerio');
var fs = require('fs');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var routes = require('./routes/index');
var app = express();
var port = process.env.PORT || 5000
var server = http.createServer(app)
server.listen(port)
console.log("http server listening on %d", port)
var WebSocketServer = require('ws').Server
var wss = new WebSocketServer({server: server})
console.log("websocket server created")
wss.on("connection", function(ws) {
fs.readFile('./playlist.json', 'utf-8', function(err, data){
if (err) throw err;
ws.send(data);
console.log(data);
});
console.log("websocket connection open")
ws.on("close", function() {
console.log("websocket connection close")
})
})**
And client-side:
var host = location.origin.replace(/^http/, 'ws')
var ws = new WebSocket(host);
ws.onmessage = function (event) {
playthelistclient.push(event.data);
};
My bin/www file part concerning ports:
var port = normalizePort(process.env.PORT || '3000');
app.set('port', port);
Hope you guys can help.

Answer 1

Comment out the stuff related to ports in www file, because you already have that stuff in your app.js file:
//var port = normalizePort(process.env.PORT || '3000');
//app.set('port', port);
//server.listen(port);
