Keep having issues serializing and deserializing my PassportJS users - express

Question

I'm using sequelize.js for my data store and the github strategy with passport.js. My code is:
app.use(passport.initialize());
app.use(passport.session());
passport.use(new GitHubStrategy({
clientID: '123',
clientSecret: '456',
callbackURL: "" + config.hostname + ":" + config.port + "/auth/github/callback"
}, function(accessToken, refreshToken, profile, done) {
var authProviderQuery, newUser;
console.log('accessToken');
console.log(accessToken);
authProviderQuery = {
authId: profile.id
};
newUser = {
name: profile.username,
email: profile.emails[0].value
};
return DB.AuthProvider.find(authProviderQuery).complete(function(err, dbAuthProvider) {
var prop, _results;
if (err) {
return done(err);
}
if (!dbAuthProvider) {
return DB.User.create(newUser).complete(function(err, dbUser) {
var newAuthProvider;
if (err) {
return done(err);
}
newAuthProvider = {
name: 'github',
oathToken: accessToken,
authId: profile.id,
rawJSON: profile._raw
};
return dbUser.createAuthProvider(newAuthProvider).complete(function(err) {
if (err) {
return done(err);
}
return done(null, dbUser);
});
});
} else {
console.log(dbAuthProvider);
_results = [];
for (prop in dbAuthProvider) {
_results.push(console.log(prop));
}
return _results;
}
});
}));
passport.serializeUser = function(user, done) {
return done(null, user.id);
};
passport.deserializeUser = function(obj, done) {
return DB.User.find({
where: {
id: obj.id
}
}).complete(function(err, dbUser) {
console.log(dbUser);
return done(err, dbUser);
});
};
app.get('/auth/github', passport.authenticate('github'));
app.get("/auth/github/callback", passport.authenticate('github', {
failureRedirect: "/login"
}), function(req, res) {
return console.log('authenticated');
});
When I go to /auth/github, I get the following error:
/Users/mysite/node_modules/mysql/lib/protocol/Parser.js:82
throw err;
^
TypeError: object is not a function
What am I doing wrong?

You are replacing the serializeUser and deserializeUser methods from Passport instead of calling them to assign a (de)serializer - ie. you have
passport.deserializeUser = function(obj, done) {
...
};
when you should have
passport.deserializeUser(function(obj, done) {
...
});
See the documentation: http://passportjs.org/guide/configure/
