RangeError [ERR_HTTP_INVALID_STATUS_CODE]：无效的状态代码：[object Object] 错误表达 4.16

Question

I'm implementing a password reset and when clicking on the generated link I'm getting the following error,

Thu Jan 25 2018 16:54:38 GMT+0000 (GMT): GET /users/reset/d590c54753abc449cfcd8aefceb8d519fce4b627

Here are my routes

// Token URL :get
router.get('/users/reset/:token', (req, res) => {
  User.findOne({
    resetPasswordToken: req.params.token,
    resetPasswordExpires: { $gt: Date.now() }
  }, function(err, user) {
    if (!user) {
      req.flash('error', 'Password reset token is invalid or has expired.');
      res.redirect('/users/forgot');
    }

    res.redirect('reset.hbs', {
      pageTitle: 'Reset Your Password',
      user: req.user
    });
  });
});

// Token URL :post
router.post('/users/reset/:token', (req, res, next) => {
  if(req.body.password === req.body['password-confirm']) {
    next();
    return;
  }

  req.flash('error', 'Passwords do not match!');
  res.redirect('back');

  User.findOne({
    resetPasswordToken: req.params.token,
    resetPasswordExpires: { $gt: Date.now() }
  }, function(err, user) {
    if(!user) {
      req.flash('error', ' Password reset is invalid or has expired');
      res.redirect('/login');
    }

    const setPassword = promisify(user.setPassword, user);
    setPassword(req.body.password);
    user.resetPasswordToken = undefined;
    user.resetPasswordExpires = undefined;
    const updatedUser = user.save();
    req.login(updatedUser);
    req.flash('success_msg', 'Your password has been reset successfully! You are now logged in!');
    res.redirect('/dashboard');
  });
});

I think, I'm close to getting this to work, just a few errors I'm running into. This being one of them. I have checked the documentation and I'm not seeing anything mentioning status codes, I believe this is a change in the recent framework, seems quite odd having to define a status code for every redirect or render.

You have to use res.render instead of res.redirect :

res.render('reset.hbs', {
  pageTitle: 'Reset Your Password',
  user: req.user
});

res.redirect method accept the route string as arguement while res.render accept a string that represent the file path of the view to render
