this is where its happening

app.models[data.model].findOne({
where : {email: req.user.email},
include : ['accessTokens']
}, function (err, user) {
if (err) {
return next(err);
}
var action;
if (!user) {
action = createUser;
} else if (user.accessTokens().length === 0) {
action = loginUser;
} else {
action = user.accessTokens.findOne;
}
