SANE stack and Passportjs

I am using the sane stack and I would like to add passportjs to it.

I successfully implemented passportjs in a sails application using the instructions here. I am trying to use those instruction to add passportjs to a sane application. I am also considering trying to have sails serve the login, logout, ect... pages, since the those instructions use sails' views. This might not be the best decision going forward, but right now I just want something that works.

I have been getting the following error when I go to login.

error: Sending 500 ("Server Error") response:

The problem is with following code in server/api/controllers/AuthController.js

 33   login: function (req, res) {
 34     var strategies = sails.config.passport
 35       , providers  = {};
 36
 37     // Get a list of available providers for use in your templates.
 38     Object.keys(strategies).forEach(function (key) {
 39       if (key === 'local') {
 40         return;
 41       }
 42
 43       providers[key] = {
 44         name: strategies[key].name
 45       , slug: key
 46       };
 47     });
 48
 49     // Render the `auth/login.ext` view
 50     res.view({
 51       providers : providers
 52     , errors    : req.flash('error')
 53     });
 54   },

And also the following code in /server/api/policies/passport.js

 24 module.exports = function (req, res, next) {
 25   // Initialize Passport
 26   passport.initialize()(req, res, function () {
 27     // Use the built-in sessions
 28     passport.session()(req, res, function () {
 29       // Make the user available throughout the frontend
 30       res.locals.user = req.user;
 31
 32       next();
 33     });
 34   });
 35 };

Any help would greatly be appreciated.
