Node Express.js 4 Route Not working, Getting 404

Question

I've been trying to debug my route in my express app. The request is undefined but not sure why.

I'm using Express 4.0 but running it Express 3.0 style (no bin/www).

server.js

    var app = require('./app')

    var port = process.env.PORT || 3000;

    app.set('port', port);

app.listen(app.get('port', function(){
    console.log('Express web server is listening on port ' + app.get('port'));
}));

app.js

var express = require('express'),
    path = require('path'),
    routes = require('./routes/index'),
    app = express();

app.use('/', routes);

app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

app.use(express.static(path.join(__dirname, 'public')));

module.exports = app;

routes/index.js

var express = require('express');
var router = express.Router();

router.get('/', function(req, res) {
    res.render('index', { title: 'Express' });
});

module.exports = router;

When I run debug on my app in webstorm, the page throws a 404 page not found. When I looked at the debug, here's the problem, the http request is undefined:

Make sure your app.listen... looks as follows

app.listen(app.get('port'), function() {
    console.log('Express web server is listening on port ' + app.get('port'));
});
