NodeJS + ExpressJS + RedisStore Session is undefined - node.js

Question

I've gone through many questions with the same issue, but none of the various solutions have helped. I'm using Redis to store session in a clustered NodeJS+ExpressJS application, but the session is always undefined. Here's my Express setup:
var express = require('express'),
RedisStore = require('connect-redis')(express),
Config = require('./config/config'),
cluster = require("cluster"),
QueryManager = require('./service/query_manager'),
app = express();
// --- Index --- //
function renderSplash(req, res) {
res.render(...);
}
function renderIndex(req, res) {
res.render(...);
}
app.get('/', function(req, res) {
if(req.session.user === null) {
renderSplash(req, res);
} else {
renderIndex(req, res);
}
});
// --- Configuration ---//
//EJS
app.engine('.html', require('ejs').__express);
app.set('view engine', 'html');
app.set('views', __dirname + '/public');
app.configure(function() {
//Session
app.use(express.cookieParser());
app.use(express.session({
store: new RedisStore({
host: Config.redis.host,
port: Config.redis.port
}),
secret: 'Its a secret.',
cookie: { secure: true }
}));
app.use(validateRequest); //Ensures we're at www. to hit the LB
app.use(express.static(__dirname+'/public'));
app.use(express.compress);
app.use(app.router);
});
Even without using the Redis store, I'm getting the following error:
TypeError: Cannot read property 'user' of undefined

You'll have to instantiate the sessions before the routes.
var express = require('express'),
RedisStore = require('connect-redis')(express),
Config = require('./config/config'),
cluster = require("cluster"),
QueryManager = require('./service/query_manager'),
app = express();
app.use(express.cookieParser());
app.use(express.session({
store: new RedisStore({
host: Config.redis.host,
port: Config.redis.port
}),
secret: 'Its a secret.',
cookie: { secure: true }
}));
// --- Index --- //
function renderSplash(req, res) {
res.render(...);
}
function renderIndex(req, res) {
res.render(...);
}
app.get('/', function(req, res) {
if(req.session.user === null) {
renderSplash(req, res);
} else {
renderIndex(req, res);
}
});
