Custom authentication callback not receiving error

[wlingke]

I am using a local authentication strategy and I am using the custom callback such as so:

router.post('/create_account',
    function (req, res, next) {
        passport.authenticate('local-signup', function (err, user, info) {
            if (err) {
                console.log("error found")
                return next(err);
            }

            //custom callback requires manually creating the session
            req.login(user, function (err) {
                if (err) {
                    return next(err)
                }
                return res.send(200);
            });
        })(req, res, next);
    }
);

However, it seems that if there is an error and I invoke done(error) where error is non-null, in configuration of the strategy, the passport.authenticate's callback never gets called. In other words, I never see the "error found" log. Instead, the error goes straight to my final error handler.

This is how the configuration looks:

passport.use('local-signup', new LocalStrategy({
                usernameField: 'email',
                passwordField: 'password',
                passReqToCallback: true
            },
            function (req, email, password, done) {
                var newUser = new User();
                // save the user
                newUser.save(function (err) {
                    if (err) {
                        //********Assume Error occurs here!*******
                        return done(err)
                    }
                    done(null, newUser);
                });

            })
    );
