node.js - Passport.js always executing "failureRedirect" -

first of all, i'm new passport.js maybe ends being naïve question. have strategy signup:

// configuring passport var passport = require('passport'); var expresssession = require('express-session'); var localstrategy = require('passport-local').strategy; var facebookstrategy = require('passport-facebook'); app.use(expresssession({secret: 'mysecretkey'})); app.use(passport.initialize()); app.use(passport.session()); app.use(flash());  //[...]    passport.use('signup', new localstrategy({      name : 'name',      password : 'password',      email : 'email',      passreqtocallback : true     },    function(req, username, password, done) {      findorcreateuser = function(){        // find user in mongo provided username        user.findone({'name':username},function(err, user) {          // in case of error return          if (err){            console.log('error in signup: '+err);            return done(err);          }         // exists       if (user) {             console.log('user exists');             return done(null, false,             req.flash('message','user exists'));          } else {            // if there no user email            // create user            var newuser = new user();            // set user's local credentials            newuser.name = name;            newuser.password = createhash(password);            newuser.email = req.param('email');            /*newuser.firstname = req.param('firstname');            newuser.lastname = req.param('lastname');*/             // save user            newuser.save(function(err) {              if (err){                console.log('error in saving user: '+err);                throw err;              }              console.log('user registration succesful');              return done(null, newuser);            });          }        });     };      // delay execution of findorcreateuser , execute     // method in next tick of event loop     process.nexttick(findorcreateuser);   })  ); 

and how deal post on /register:

/* handle registration post */ app.post('/register', passport.authenticate('signup', {   successredirect: '/',   failureredirect: '/failure_registration',   failureflash : true })); 

this always brings me failureredirect link, instead of success. input data correct, , i'm using different user , mail register. i'm sorry if stupid question, don't understand why never goes successredirect.

thanks.

edit: added suggestion , corrections @robertklep, still not working. i'd point out no error triggered, nor log printed.

edit2: serialization/deserialization functions:

passport.serializeuser(function(user, done) {     done(null, user.id); });  passport.deserializeuser(function(id, done) {     user.findbyid(id, function (err, user) {         done(err, user);     }); }); 

i had same problem, failureredirect being executed

first diagnose, used custom callback method http://passportjs.org/docs/authenticate

app.post('/sign_in', function(req, res, next) {     console.log(req.url);     passport.authenticate('local-login', function(err, user, info) {         console.log("authenticate");         console.log(err);         console.log(user);         console.log(info);     })(req, res, next); }); 

then see hidden error was

authenticate null false { message: 'missing credentials' } 

which became easy me diagnoise, sending json in request rather form fields

fixed changing

app.use(bodyparser.urlencoded({ extended: true })); 

to

app.use(bodyparser.json());
