Unable to grab data from MongoDB to use on Express - node.js

Question

I'm currently trying to grab data from MongoDB via Mongoose, and show it with Express. However, this is the following error I'm getting:
TypeError: /home/node/CSci-Project/views/account.ejs:31
29| <% if (req.user.twitter.token) { %>
30| <p>
>> 31| <strong>id</strong>: <%= user.twitter.id %><br>
32| <strong>token</strong>: <%= user.twitter.token %><br>
33| <strong>display name</strong>: <%= profile.twitter.displayName %><br>
34| <strong>username</strong>: <%= profile.twitter.username %><br>
Cannot read property 'twitter' of undefined

I thought I had passed it through with callback and with findOne being asynchronous, so I'm not sure where to go from here. Here are the relevant files:
views/account.ejs (the page I'm trying to view)
app/routes.js
app/models/user.js
app/models/profile.js
Sorry if I've made any simple mistakes in here - I'm new to Node and I've come over from C#, so I'm still in the process of learning the differences. Also worth noting that data is definitely on MongoDB and it all exists.

Well, I managed to figure it out, after countless attempts. My mistake was that I thought by putting var userInfo = UserModel.findOne it would just simply print itself out as userInfo.id, userInfo.token, etc, but no. I actually meant to use the output that's inside of UserModel.findOne.
app/routes.js
module.exports = function (app, passport) {
app.get('/account', isLoggedIn, function (req, res) {
var UserModel = require('./models/user.js');
var ProfileModel = require('./models/profile.js');
UserModel.findOne({
'twitter.id': req.user.twitter.id
}, function (err, userInfo) {
if (err) {
return res.redirect('/');
} else {
ProfileModel.findOne({
'twitter.id': req.user.twitter.id
}, function (err, profileInfo) {
if (err) {
return res.redirect('/');
} else {
res.render('account.ejs', {
req: req,
user: userInfo,
profile: profileInfo
});
}
});
}
});
});
};
