How did those specified in the settings output errors in the passport-local-mongoose module?

Question

Node.js

I have a question, I did authorization using this passport-local-mongoose module and there was such a problem that I can’t figure out how to make the errors that I specified in the options of the module display them, and didn’t I write these errors myself in the message?

router.post('/', (req, res) => {
  let authenticate = User.authenticate();
  authenticate(req.body.username, req.body.password, (err, result) => {
    if (err) {
      console.log(err);
      return res.render('index', {message: err})
    }
    if (result === false){
            return res.render('index', {message: 'Неверный логи или пароль'})
    }
        passport.authenticate('local')(req, res, function () {
            res.redirect('/users');
        });
  })
});

And in the model I specified the plugin connection

let mongoose = require('../bin/mongoose'),
  passportLocalMongoose = require('passport-local-mongoose'),
  Schema = mongoose.Schema;

let schema = new Schema({
  username: {
    type: String,
  },
  password: {
    type: String,
  },
  created: {
    type: Date,
    default: Date.now
  }
});

schema.plugin(passportLocalMongoose, {
  errorMessages: {
    UserExistsError: 'Данный пользователь уже зарегестрировался',
        IncorrectPasswordError: 'Неправильный логин или пароль',
        IncorrectUsernameError: 'Неправильный логин или пароль'
    }
});

module.exports = mongoose.model('User', schema);

That's what I didn't have so that it would display an IncorrectPasswordError error, and not result false. At least I didn't find any answers. Can someone help me figure it out
