My discord.js file

const passport = require('passport');
const DiscordStrategy = require('passport-discord').Strategy;
const scopes = ['identify', 'email', 'guilds', 'guilds.join'];
const Users = require('./../models/user');

passport.serializeUser(function(user, done) {
cnsole.log(user)
  done(null, user);
});
passport.deserializeUser(function(obj, done) {
  console.log(obj)
  done(null, obj);
});
passport.use(new DiscordStrategy({
    clientID: '**************',
    clientSecret: process.env.secret,
    callbackURL: 'https://************/auth/discord/callback',
    scope: scopes
},
 async function(accessToken, refreshToken, profile, cb) {
   console.log(accessToken, refreshToken, profile, cb)
}));

Auth.js

const express = require('express');
const router = express.Router()
const passport = require('passport');

router.get('/discord', passport.authenticate('discord'));
router.get('/discord/callback', passport.authenticate('discord', {
    failureRedirect: '/'
}), function(req, res) {
    res.redirect('/secretstuff') // Successful auth
});

module.exports = router;

What am I doing wrong here??

It got fixed by adding a code_verifier and code parameter by using crypto module
