Passport LocalStrategy never called on Express

Question

I wrote console.log in LocalStrategy callback but it never called. I use Sequelize for ORM (MySQL).

passport.js

const LocalStrategy = require('passport-local').Strategy
const passport = require('passport')
const bcrypt = require('bcrypt')
const UrunModel = require('../models/Urun')

console.log('File is Called') // If my require is wrong. But this log worked.    

passport.use(new LocalStrategy({
    usernameField: 'mail',
    passwordField: 'pw1'
},
    (username, password, done) => {
      console.log('Worked!') // Never Called
      UrunModel.findOne({
          where : {
              UrunName : 'testuser',
              UrunDesc : '123456'
          }
      })
    }
));

passport.serializeUser(function(user, done) {
    done(null, user.id);
  });
  
  passport.deserializeUser(function(id, done) {
    User.findById(id, function(err, user) {
      done(err, user);
    });
  });

index.js

const session = require('express-session');
const bodyParser = require('body-parser')
const urlencoded = bodyParser.urlencoded({extended:false})
const passport = require('passport')

app.use(session({
  secret: 'keyboardSecrIncKey',
  resave: false,
  saveUninitialized: true,
}))

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

require('./config/passport') //require my passport.js

app.post('/test',(req,res,next) => {
  passport.authenticate('local',{
    successRedirect: '/worked',
    failureRedirect: '/notworked'
  })(req,res,next)
})

It redirect me '/notworked' url. I watched 3 or 4 videos but almost same on my code.

Where i am failed ? Please explain my fault.

By default, LocalStrategy expects to find credentials in parameters named username and password. If your site prefers to name these fields differently, options are available to change the defaults.

you use mail and pw1 parameters , check req.body, because req.body don't have this parameters in the body.

your issue will be solve if you replace

{
    usernameField: 'mail',
    passwordField: 'pw1'
}

with

{
    usernameField: 'username',
    passwordField: 'password'
}

Also you can check the documentation
