Error on redirect

[peili]

I get the following error when using:
req.flash('info', 'You are an awesome admin because you use flashify');
return res.redirect("/");

/Users/peili/node_modules/meeting/node_modules/mongoose/lib/utils.js:413
throw err;
^
TypeError: Object function (e) {
var t, _ref;
if ((t = this.indexOf(e)) > -1) {
return ([].splice.apply(this, [t, t - t + 1].concat(_ref = [])), _ref);
}
} has no method 'forEach'

Is this still a problem ?
