Automatic failureRedirect in Passport - node.js

Question

I have a problem with my code. When I am trying to login without insert username and password
POST /user/login 302 1.289 ms - 32
GET /user/hehehehehe 404 6.310 ms - 1272
If i try to login with only login it's the same result
If i try to login with username and password correct or incorrect
500 Internal Server Error
Can someone tell me, where the mistake is?? That is first load failureRedirect. What is first thing I should check after trying to login??
router.post('/create', function (req, res, next) {
var newUser = {
username: req.body.username,
password: req.body.password
}
console.log(req.body)
req.checkBody('username', 'Login is required').notEmpty();
req.checkBody('password', 'Password is required').notEmpty();
var errors = req.validationErrors();
if (errors) {
console.log(errors)
res.send(errors);
} else {
bcrypt.hash(newUser.password, saltRounds, function (err, hash) {
if (err) {
console.log(err)
} else {
newUser.password = hash;
var user = new User(newUser);
user.save()
.then(function (User) {
res.send(User);
})
}
});
req.flash('success_msg', 'You are registered and can now login');
//res.redirect('/');
}
});
passport.use(new LocalStrategy(
function(username, password, done) {
User.getUserByUsername(username, function(err, user){
if(err) throw err;
if(!user){
return done(null, false, {message: 'Unknown User'});
}
User.comparePassword(password, user.password, function(err, isMatch){
if(err) throw err;
if(isMatch){
return done(null, user);
} else {
return done(null, false, {message: 'Invalid password'});
}
});
});
}));
passport.serializeUser( function(user, done) {
console.log('eheheheheh');
done(null, user.id);
});
passport.deserializeUser( function(id, done) {
User.getUserById(id, function(err, user) {
console.log('eheheheheh');
done(err, user);
});
});
router.post('/login',
passport.authenticate('local', { successRedirect:'hahahha', failureRedirect:'hehehehehe', failureFlash: true }),
function(req, res) {
console.log('yyy'),
res.redirect('dydydydy');
});
IMPORTANT
Which functions are loaded first?
1 - /login
Then this code?
passport.use(new LocalStrategy(
function(username, password, done) {
User.getUserByUsername(username, function(err, user){
if(err) throw err;
if(!user){
return done(null, false, {message: 'Unknown User'});
}
User.comparePassword(password, user.password, function(err, isMatch){
if(err) throw err;
if(isMatch){
return done(null, user);
} else {
return done(null, false, {message: 'Invalid password'});
}
});
});
}));
What mistakes might be here??
