尝试使用 bcrypt 将用户保存到 mySql 中。但返回错误：需要数据和盐参数

尝试使用 bcrypt 将用户保存到 mySql 中。但返回错误：需要数据和盐参数。

这是我的代码

授权控制器：

export const register = (req, res) => {
//CHECK EXISTING USER
const q = "SELECT * FROM user WHERE email = ? OR username = ?";

db.query(q, [req.body.email, req.body.username], (err, data) => {
    if (err) return res.status(500).json(err);
    if (data.length) return res.status(409).json("User already exists!");

    //Hash the password and create a user
    const salt = bcrypt.genSaltSync(10);
    const hash = bcrypt.hashSync(req.body.password, salt);

    const q = "INSERT INTO users(`username`,`email`,`password`) VALUES (?)";
    const values = [req.body.username, req.body.email, hash];

    db.query(q, [values], function (err, data) {
        if (err) return res.status(500).json(err);
        return res.status(200).json("User has been created.");
    });
  });

};

如你所见，我已经定义了salt和hash by

const salt = bcrypt.genSaltSync(10);

 const hash = bcrypt.hashSync(req.body.password, salt);

所以我不知道为什么返回 Error: data and salt arguments required.

这里是返回的错误：
