hello there I am new in learning about mongoDB,node js,Passport and express actually I was succefully able to create a working signup page but my problem is the sigin page like every time I am trying to enter correct email and password it always go to failure to redirect knwoing that this is my code for the routers
users.js

var express = require('express');
var router = express.Router();

const { check, validationResult } = require('express-validator');
const User = require('../models/User');
const passport = require('passport');


/* GET users listing. */
router.get('/signup', function (req, res, next) {
  var massagesError = req.flash('error')
  res.render('signup', { massages: massagesError })
});

router.post('/signup', [
  check('name').not().isEmpty().withMessage('Please Enter Your Name'),


  check('email').not().isEmpty().withMessage('Please Enter Your Email'),
  check('email').isEmail().withMessage('Please Enter Valid Email'),

  check('password').not().isEmpty().withMessage('Please Enter your Password'),
  check('password').isLength({ min: 8 }).withMessage('Please Enter Password more than 8 characters'),
  check('confirm-password').custom((value, { req }) => {
    if (value !== req.body.password) {
      throw new Error('Password and confirm-password do not match');
    }
    return true;
  }),

  check('phoneNumber').not().isEmpty().withMessage('Please Enter your Phone Number'),
  check('phoneNumber').isMobilePhone().withMessage('please enter Valid Phone Numeber'),

  check('userType').isIn(['sponsor', 'student']).withMessage('Please select a valid user type')

], (req, res, next) => {
  const errors = validationResult(req);
  if (!errors.isEmpty()) {


    var validationMassages = [];
    for (var i = 0; i < errors.errors.length; i++) {
      validationMassages.push(errors.errors[i].msg)
    }

    req.flash('error', validationMassages);
    res.redirect('signup')



    console.log(validationMassages);

    return;
  }
  const user = new User({
    name: req.body.name,
    email: req.body.email,
    password: new User().hashPassword(req.body.password),
    phoneNumber: req.body.phoneNumber,
    userType: req.body.userType

  })

  User.findOne({ email: req.body.email })
    .then(result => {
      if (result) {
        // User with the provided email already exists

        req.flash('error', 'this email already exist')
        res.redirect('signup')
        return;
      }
      user.save()
        .then(doc => {
          res.send(doc);
        })
        .catch(error => {
          console.log(error);
          res.status(500).send('An error occurred while saving the user');
        })
    })





})



router.get('/profile', (req, res, next) => {
  res.render('profile')
});




router.get('/signin', (req, res, next) => {
  res.render('signin');
})

router.post('/signin', passport.authenticate('local-signin', 
{session:false,
  successRedirect: 'profile',
  failureRedirect: 'signin',
  failureFlash : true,
}))




module.exports = router;

and this for the passport
passport.js

const passport = require('passport');
const localStrategy = require('passport-local').Strategy;
const User = require('../models/User');

passport.use('local-signin', new localStrategy({
    usernameField: 'email', // default is username, override to accept email
    passwordField: 'password',
    passReqToCallback: true // allows us to access req in the call back
  }, async (req, email, password, done) => {
    // Check if user and password is valid
    let user = await User.findBy('email', email)
    let passwordValid = user && bcrypt.compareSync(password, user.passwordHash)

    // If password valid call done and serialize user.id to req.user property
    if (passwordValid) {
      return done(null, {
        id: user.id
      })
    }
    // If invalid call done with false and flash message
    return done(null, false, {
      message: 'Invalid email and/or password'
    });

}))

and this is my app.js

var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
const mongoose = require('mongoose');
const expressHbs = require('express-handlebars');
const session = require('express-session');
const flash = require('connect-flash');
const passport =require('passport');

var indexRouter = require('./routes/index');
var usersRouter = require('./routes/users');

var app = express();



require('./config/passport');



// view engine setup
app.engine('.hbs', expressHbs.engine({defaultLayout : 'layout' , extname : '.hbs'}));
app.set('view engine', '.hbs');

app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));


app.use(cookieParser());
app.use(session({
  secret : 'Chance_?@!',
  saveUninitialized : false,
  resave : false,
}));

app.use(passport.initialize());
app.use(passport.session());
app.use(flash());

app.use(express.static(path.join(__dirname, 'public')));







mongoose.connect('mongodb://localhost/Chance')
  .then(() => {
    console.log('Connected to MongoDB successfully!');
    // You can perform further operations with the connected database here
  })
  .catch(error => {
    console.error('Failed to connect to MongoDB:', error);
  });



app.use('/', indexRouter);
app.use('/users', usersRouter);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  console.log('Requested URL:', req.url); // Add this line to log the requested URL
  next(createError(404));
});

// error handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error');
});

module.exports = app;
