如何获取服务器节点js错误？

我在Node.js和Express中构建了auth应用程序。现在，我正在编写后端。我使用MongoDB数据库。

我使用发布查询来登录带有下一个JSON数据的页面。出现错误-电子邮件字段必须用双引号引起来，但我希望该服务器不会崩溃，并通过错误向我回复

我具有下一个功能：

const bcrypt = require('bcryptjs')
const User = require('../model/User')
const authHelper = require('../helpers/authHelper')
const config = require('../config')

module.exports = async (req, res) => {

  try {
    const {
      email,
      password
    } = req.body

    if(!(email || password)) {
      throw new Error('Enter the properties correctly')
    }

    const user = await User.findOne({
      email
    })
    if (!user) return res.status(400).json({
      message: 'Email or password is wrong'
    })

    const validPass = await bcryptpare(password, user.password)
    if (!validPass) return res.status(400).json({
      message: "Email is not found"
    })

    const accessToken = authHelper.generateAccessToken(user._id).token
    const refreshToken = authHelper.generateRefreshToken(user._id).token

    // res.set({
    //   "access-token": accessToken.token,
    //   "refresh-token": refreshToken.token,
    // })

    return res.json({
      "accessToken": accessToken,
      "refreshToken": refreshToken,
    })
  } catch (e) {
    return res.json({
      msg: e.message
    })
  }
}

这里是查询

{
    email: "[email protected]",
    "password": "test"
}

错误消息：

SyntaxError: Unexpected token e in JSON at position 3
at JSON.parse (<anonymous>)
at parse (R:\Projects\jwt-auth\node_modules\body-parser\lib\types\json.js:89:19)

尝试修复电子邮件密钥：

{
    "email": "[email protected]",
    "password": "test"
}

JSON对象密钥必须在双行之间。
