PassportJS and ExpressJS conditional URL redirect

I am using ExpressJS and PassportJS's Facebook strategy to try and perform some conditional redirects on the authentication callback that should be called when certain properties are missing.

My User Schema:

var UserSchema = new Schema({
  id: ObjectId,
  uid: String,
  facebookToken: String,
  username: String,
  password: String,
  salt: String,
  firstName: String,
  lastName: String,
  email: String,
  birthday: Date,
  gender: String,
  location: String,
  phone: Number,
  verifiedPhone: Boolean,
  interests: {
    culture: Boolean,
    food: Boolean,
    business: Boolean,
    family: Boolean,
    learning: Boolean,
    sports: Boolean,
    movies: Boolean,
    music: Boolean,
    events: Boolean,
    nightlife: Boolean,
    health: Boolean,
    beauty: Boolean,
    fashion: Boolean,
    motoring: Boolean,
    electronics: Boolean,
    groceries: Boolean,
    travel: Boolean,
    decor: Boolean
  },
  weeklyNotifcation: Number,
  weeklyNotificationSent: Number,
  created: {type: Date, default: Date.now}
});

My Callback:

app.get('/auth/facebook/callback', passport.authenticate('facebook', { failureRedirect: '/login' }), function(req, res) {
  User.findOne({uid: req.session.uid}, function(err, user) {
    if(user.email || user.location || user.phone || user.location == undefined) {
      res.redirect('/register');
    } else {
      res.redirect('/');
    }
  });
});

The data is stored into mongo after /auth/facebook is called. I check the DB against using the session and check to see if it undefined as it will not return the fields since they weren't stored in the DB. The callback fails and returns no data received.

Any help will be appreciated.
