nodejs/express - cannot load routes using passport - node.js

Question

I am trying to use passport to add user sessions on my webapp. I have configure my main js file as follow:
/**
* Module dependencies.
*/
var express = require('express');
var user = require('./server/routes/user');
var routes = require('./server/routes/index');
var http = require('http');
var path = require('path');
var app = express();
var passport = require('passport');
var flash = require('connect-flash');
require('./server/config/passport')(passport); // pass passport for configuration
// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(app.router);
app.use(require('stylus').middleware(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'public')));
app.configure(function(){
// required for passport
app.use(express.session({ secret: 'ilovesefounders' })); // session secret
app.use(passport.initialize());
app.use(passport.session()); // persistent login sessions
app.use(flash()); // use connect-flash for flash messages stored in session
})
// routes ======================================================================
require('./server/routes/index')(app, passport); // load our routes and pass in our app and fully configured passport
routes.mount(app);
However when i try to launch it I get the following error:
require('./server/routes/index')(app, passport); // load our routes and pass i
^
TypeError: object is not a function

What's going wrong here?

I don't know how your index.js looks like but you probably did not export your function module.
Check if index.js looks something like this:
module.exports = function(app, passport) {
/* code */
};
And you don't need to require "./server/routes/index" again.
