Question

我的代码工作正常，但是我从哪里开始出现此错误。 ReferenceError：下一个未定义。不知道如何开始获取它，因为我根本没有更改此功能。

const Accounts = require('../data/accounts.model')

exports.addAccount = (req, res) => {
    const newAccount = new Accounts({
        Username: req.body.Username,
        Password: req.body.Password,
        AccountType: req.body.AccountType,
        Email: req.body.Email,
        Age: req.body.Age,
        Question1A: req.body.Question1A,
        Question2A: req.body.Question2A,
        Question3A: req.body.Question3A,
    });

    newAccount.save((err) => {
        if (err){
             return next(err);
  //error happens here^
        }
        res.send('Account created Successfully');
    });
};

next是任何中间件的第三个参数。因此代码应为：

exports.addAccount = (req, res, next) => {

控制器功能，下一个未定义错误
