Auth handling breaking with Node.js Integration module

When I connect with more than one authenticated user in a chatroom my server.js running from the node.js integration module crashes. I would create this ticket under the Node.js module project but I think the problem is with how chatroom handles the code, I'm not entirely sure though.

I run other modules, like tic tac toe, that handle multiple users no problem, so I don't think the error is with server.js, I could be wrong.
