Can't get sessions to work - TypeError: Cannot set property 'uid' of undefined

[Anthony Crognale]

Hello all,

I've been having trouble with getting sessions to work on express
2.0.0beta with connect 1.0.3. I've tried using connect-redis, connect-
mongodb, and even memorystore to no avail. Here's the issue:

I'll try and set a session property like "req.session.uid = user._id",
but then node returns (anywhere I try it):

TypeError: Cannot set property 'uid' of undefined
at Object.<anonymous> (/home/ubuntu/impromptu/app.js:257:22)
at param (/usr/local/lib/node/.npm/connect/1.0.3/package/lib/

http.js:204:15)
at Object.methodOverride [as handle] (/usr/local/lib/node/.npm/
connect/1.0.3/package/lib/middleware/methodOverride.js:35:5)

I've tried reinstalling node, express, connect, etc and even putting
it on a different server with the same versions - still no luck.

Using node 0.4.2, connect 1.0.3, express 1.0.7. Date and time are set
correctly on the server for what it's worth...

Any ideas? Can provide more info if needed. Here's my app.configure:

app.configure( function() {
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(__dirname + '/public'));
app.use(express.cookieParser());
app.use(express.session({store: memStore({reapInterval: 60000 *
10}) , secret: 'is a secret'}));
});
app.configure('development', function() {
app.use(express.errorHandler({ dumpExceptions: true, showStack:
true }));
});

(var memStore = require('connect').session.MemoryStore;)

I had the exact same problem.  I was unable to get connect-mongodb to work with connect 1.0 and the developer of connect-mongodb is not longer supporting it so im not sure if that is ever gonna get fixed (or even if it needs to, we may be both doing something else wrong). 

However, I was able to get sessions working with express, just not into mongo or redis. I beleive it depends on the order of setting the session call in your config.  You can see my configuration below, which works in express 2.0-beta, node 0.50-pre and Connect 1.0.3:

app.use(express.static(__dirname + '/public'));
app.use(express.favicon());
app.use(express.bodyParser());
app.use(express.cookieParser());

app.use(express.methodOverride());
        app.use(express.session({ secret: 'topsecret' }));
app.use(app.router);
      app.use(stylus.middleware({
        src: __dirname + '/public'
      , dest: __dirname + '/public'
      , compile: compile 
    }));

I think it breaks with app.router being called before express.session. Hope that helps.

That would do it, yes; if app.router is installed before express.session, it means the session middleware wont be run until after your routes have fired. Therefore, req.session isn't set up until afterwards, either.

Thanks so much, that fixed it right up. Glad it was as simple as that, now
to figure out what to do about my session store.

If you find a solution for mongodb session stores, pleas let us know.
I too am looking for a connect-mongodb replacement.

you cannot use express < 2.0 with connect 1.x
