Google-oauth2 passport not working - node.js

Question

I am trying to implement sign-in with google and passport but I am running into a bit of a problem. I successfully authenticate with google, but my data isn't being passed to the front end. I Haven't changed anything from the original code except for the URI and necessary client id and secret. Can anyone tell me what I am missing?
var express = require( 'express' )
, app = express()
, server = require( 'http' ).createServer( app )
, passport = require( 'passport' )
, util = require( 'util' )
, bodyParser = require( 'body-parser' )
, cookieParser = require( 'cookie-parser' )
, session = require( 'express-session' )
, RedisStore = require( 'connect-redis' )( session )
, GoogleStrategy = require( 'passport-google-oauth2' ).Strategy;
// API Access link for creating client ID and secret:
// https://code.google.com/apis/console/
var GOOGLE_CLIENT_ID = "307841191614-1shiak514mrjugtbon3dm2if8hbhnvdv.apps.googleusercontent.com"
, GOOGLE_CLIENT_SECRET = "fgViegEgHWuoc1X-p63iPmpF";
// Passport session setup.
// To support persistent login sessions, Passport needs to be able to
// serialize users into and deserialize users out of the session. Typically,
// this will be as simple as storing the user ID when serializing, and finding
// the user by ID when deserializing. However, since this example does not
// have a database of user records, the complete Google profile is
// serialized and deserialized.
passport.serializeUser(function(user, done) {
done(null, user);
console.log("User: "+ user.displayName); // If there is a persistent session, the console logs out the displayName
});
passport.deserializeUser(function(obj, done) {
done(null, obj);
});
// Use the GoogleStrategy within Passport.
// Strategies in Passport require a `verify` function, which accept
// credentials (in this case, an accessToken, refreshToken, and Google
// profile), and invoke a callback with a user object.
passport.use(new GoogleStrategy({
clientID: GOOGLE_CLIENT_ID,
clientSecret: GOOGLE_CLIENT_SECRET,
//NOTE :
//Carefull ! and avoid usage of Private IP, otherwise you will get the device_id device_name issue for Private IP during authentication
//The workaround is to set up thru the google cloud console a fully qualified domain name such as http://mydomain:3000/
//then edit your /etc/hosts local file to point on your private IP.
//Also both sign-in button + callbackURL has to be share the same url, otherwise two cookies will be created and lead to lost your session
//if you use it.
callbackURL: "http://127.0.0.1:3000/oauth2callback",
passReqToCallback : true
},
function(request, accessToken, refreshToken, profile, done) {
// asynchronous verification, for effect...
process.nextTick(function () {
// To keep the example simple, the user's Google profile is returned to
// represent the logged-in user. In a typical application, you would want
// to associate the Google account with a user record in your database,
// and return that user instead.
console.log(profile); //logs google profile successfully
return done(null, profile);
});
}
));
// configure Express
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');
app.use( express.static(__dirname + '/public'));
app.use( cookieParser());
app.use( bodyParser.json());
app.use( bodyParser.urlencoded({
extended: true
}));
app.use( session({

app.get( '/oauth2callback',

successRedirect: '/',

}));
app.get('/logout', function(req, res){
req.logout();
res.redirect('/');
});
server.listen( 3000 );
// Simple route middleware to ensure user is authenticated.
// Use this route middleware on any resource that needs to be protected. If
// the request is authenticated (typically via a persistent login session),
// the request will proceed. Otherwise, the user will be redirected to the
// login page.
function ensureAuthenticated(req, res, next) {
if (req.isAuthenticated()) { return next(); }
res.redirect('/login');

Here is the simple layout that doesn't seem to be receiving any data.
<% if (!user) { %>
<h2>Welcome! Please log in.</h2>
<% } else { %>
<h2>Hello, <%= user.displayName %>.</h2>
<% } %>

Your code works, I just used same example on my app.
I had the same problem and I realized that I'm not using a valid account in my tests.
This API retrieves data from Google+ profile. Are you using a valid Google account with linked Google+ profile to authenticate?
