express-socket.io-session: Undefined

Trying to let the code speak for itself.

var express = require("express");
var app = express();
var server = require("http").createServer(app);
var io = require("socket.io")(server);
var session = require('express-session')({
    name: "session",
    secret: "lfdod9Jiru65MMl",
    saveUninitialized: true,
    resave: true,
    cookie: {
        httpOnly: false,
        maxAge: 1000 * 60 * 60 * 24
    }
});
var sharedsession = require("express-socket.io-session");

app.use(session);
io.use(sharedsession(session), {
    autoSave:true
});
io.on('connection', function(socket){
    socket.on("clicked", function(value) {
       // this does happen, I checked with console.logs
       socket.handshake.session.key = value;
    });
});
`app.get("/index", function(req, res) {
    console.log("xxx");
    console.log(req.session.key); //writes undefined
    res.render("index");
});
