如何修复与和的NodeJS MongoDB的这个语法错误

我有我的脚本语法错误，我不明白...我检查了这么多时间，请帮助

if(errors) {
          res.render('register',{
        errors:errors,
    });
  } else {
    User.findOne({ email: email }).then(user => {
      if (user) {
        req.flash('error_msg','This adress mail is already in db');
        res.render('register', {
          errors:errors
        })
  } else {
        var newUser = new User({
            email:email,
            username: username,
            password: password
        });
     User.createUser(newUser, function(err, user){
      if(err) throw err;
      console.log(user);
    });

    req.flash('success_msg', 'You create an account, u can now log');

    res.redirect('/users/login');
  }
})

在我VSCODE问题的错误：（但第126行的我最后我的网页线...）

[ts] '{' expected. [1005] (126,25)

而在我的终端

});

请帮它一点点错误，但我是个初学者，我不明白问题出在哪里..

你错过了最后}从else语句
