基本上，当我尝试登录用户时，如果输入了错误的密码或用户名，然后尝试使用正确的凭据登录，就会出现此错误。

Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client

这是我在auth.js中的代码

//LOGIN

router.post('/login', async (req, res) => {
  try {
    const user = await User.findOne({
      username: req.body.username,
    });

    !user && res.status(401).json('Wrong User Name');

    const hashedPassword = CryptoJS.AES.decrypt(
      user.password,
      process.env.PASS_SEC
    );
    const originalPassword = hashedPassword.toString(CryptoJS.enc.Utf8);

    const inputPassword = req.body.password;

    originalPassword != inputPassword && res.status(401).json('Wrong Password');

    const accessToken = jwt.sign(
      {
        id: user._id,
        isAdmin: user.isAdmin,
      },
      process.env.JWT_SEC,
      { expiresIn: '3d' }
    );

    const { password, ...others } = user._doc;
    res.status(200).json({ ...others, accessToken });
  } catch (err) {
    res.status(500).json(err);
  }
});

我该怎么办？我的代码有问题吗？
