RequestError：无效的列名节点js sql服务器通行证

Question

美好的一天，我正在使用SQL Server（MSSQL），js节点和通行证进行登录系统，用户注册表可以正常工作，但登录身份验证失败，始终返回未找到的用户，我是新手，我想得到一些指导，请在我进行身份验证的地方附上我的代码，我的代码是：文件passport.js

     passport.use('local.signin', new LocalStrategy({
     usernameField: 'username',
     passwordField: 'passwords',
     passReqToCallback: true
     }, async (req, username, passwords, done) => {
     const request=pool.request();
     //request.input('username',username);
    //request.input('passwords',passwords);
    const rows = await request.query(`SELECT * FROM signUp WHERE username=${username}`);
     console.log(passwords)
    if (rows.length > 0) {
    const user = rows[0];
    const validPassword = await   helpers.matchPassword(passwords,user.passwords)
    if (validPassword) {
      done(null, user, req.flash('success', 'Bienvenido' + user.username));
    } else {
      done(null, false, req.flash('message', 'Incorrect Password'));
    }
  } else {
    return done(null, false, req.flash('message', 'El Nombre de usuario no existe'));
}    
}));

   passport.use('local.signup', new LocalStrategy({
    usernameField: 'username',
    passwordField: 'passwords',
    passReqToCallback: true
    }, async (req, username, passwords, done) => {

    var user = {
    username : req.body.username,
    passwords :req.body.passwords
   };
   user.passwords = await helpers.encryptPassword(passwords);
   // Saving in the Database
   request.input('username',user.username);
  request.input('passwords',user.passwords);
  const result = await request.query("insert signUp values(@username,@passwords)");
   user.id = result.insertId;
   return done(null, user);
   }));

   passport.serializeUser(function(user, done) {
   done(null, user.id);
   });

  passport.deserializeUser(async (id, done)=> {
  const rows = await pool.query(`SELECT * FROM signUp WHERE id =${id}`);
  done(null, rows[0]);
  });

routes.js

// SIGNUP
router.get('/signup', (req, res) => {
  res.render('auth/signup');
});

router.post('/signup', passport.authenticate('local.signup', {
  successRedirect: '/profile',
  failureRedirect: '/signup',
  failureFlash: true
}));

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

router.post('/signin', (req, res, next) => {
  req.check('username', 'Username is Required').notEmpty();
  req.check('passwords', 'Password is Required').notEmpty();
  const errors = req.validationErrors();
  if (errors.length > 0) {
    req.flash('message', errors[0].msg);
    res.redirect('/signin');
  }
  passport.authenticate('local.signin', {
    successRedirect: '/profile',
    failureRedirect: '/signin',
    failureFlash: true
  })(req, res, next);
});

router.get('/logout', (req, res) => {
  req.logOut();
  res.redirect('/');
});

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

module.exports = router;
