对象在快递中使用护照注册时出现对象错误

我在NodeJs项目中使用Passport和Express . 我有一个用户模型，其中包含字段：id，密码和电子邮件 . 当我尝试注册时会抛出此错误：

[object Object]

进入表单，它不会在数据库中发布用户数据 . 在控制台中，它显示

POST /signup 302 -58.

这是整个passport.js文件：

var LocalStrategy    = require('passport-local').Strategy;

// load up the user model
var configDB = require('./database.js');
var Sequelize = require('sequelize');
var sequelize = new Sequelize(configDB.url);

var User       = sequelize.import('../app/models/users');
User.sync();

// load the auth variables
var configAuth = require('./auth'); // use this one for testing

module.exports = function(passport) {

    // used to serialize the user for the session
    passport.serializeUser(function(user, done) {
        done(null, user.id);
    });

    // used to deserialize the user
    passport.deserializeUser(function(id, done) {
        User.findById(id).then(function(user){
            done(null, user);
        }).catch(function(e){
            done(e, false);
        });
        });

        passReqToCallback : true // allows us to pass in the req from our route (lets us check if a user is logged in or not)
    },
    function(req, email, password, done) {      
            User.findOne({ where: { email: email }})
                .then(function(user) {
                    if (!user) {
                        done(null, false, req.flash('loginMessage', 'Unknown user'));
                    } else if (!user.validPassword(password)) {
                        done(null, false, req.flash('loginMessage', 'Wrong password'));
                    } else {

    // show the login form
    app.get('/login', function(req, res) {
        res.render('login.ejs', { message: req.flash('loginMessage') });
    });

    // process the login form
    app.post('/login', passport.authenticate('local-login', {
        successRedirect : '/profile', // redirect to the secure profile section
        failureRedirect : '/login', // redirect back to the signup page if there is an error
        failureFlash : true // allow flash messages
    }));

    // SIGNUP =================================
    // show the signup form
