NodeJs MonogoDb: NodeJs不保存更改

Question

来自findOneAndUpdate()的更新后的结果在控制台中作为请求主体返回，但是更改不会从我的前端或邮递员中保存。我已经尝试了相当多的变化，但我没有任何进展。不知道下一步该怎么走。我已经做了相当多的阅读，但遗憾的是没有结果。

useRoutes.js

require("dotenv").config();

const express = require("express");
const router = express.Router({ mergeParams: true });
const jwt = require("jsonwebtoken");
const bcryptjs = require("bcryptjs");
const cookieParser = require('cookie-parser'); 
const { check, validationResult } = require("express-validator");

const User = require("../models/userSchema");

const ObjectID = require('mongodb').ObjectID;

function asyncHandler(callback) {
  return async (req, res, next) => {
    try {
      await callback(req, res, next);
    } catch (error) {
      next(error);
      console.log(error);
    }
  };
}

//updates user account
router.patch("/user/:id",[
    check("firstName")
      .exists({ checkNull: true, checkFalsy: true })
      .withMessage('Please provide a value for "firstName"'),
    check("lastName")
      .exists({ checkNull: true, checkFalsy: true })
      .withMessage('Please provide a value for "username"'),
    check("sexualPreference")
      .exists({ checkNull: true, checkFalsy: true })
      .withMessage('Please provide a value for "sexualPreference"'),
    check("description")
      .exists({ checkNull: true, checkFalsy: true })
      .withMessage('Please provide a value for "description"'),
  ],
  asyncHandler(async (req, res, next) => {
    const errors = validationResult(req);
    if (!errors.isEmpty()) {
      const errorMessages = errors.array().map((error) => error.msg);
      return res.status(400).json({ errors: errorMessages });
    }

    const updateObject = req.body;

    console.log(req.params.id)

    await User.findOneAndUpdate({ _id: new ObjectID(req.params.id) },{ updateObject }, { new: true }, function(err, doc) {
      if(err) {
          return res.json({success: false, message: err.message});
      }
      console.log(updateObject);
      res.json({ updateObject });

      return res.status(204).end();
    });

  })
);

userSchema.js

const mongoose = require('mongoose');

const userSchema = mongoose.Schema( {

    firstName:{
        type: String,
        required: true 
    },
    lastName: {
        type: String,
        require: true
    },
    emailAddress: {
        type: String,
        require: true
    },
    password:{
        type: String,
        required: true 
    },
   gender:{
        type: String,
        required: true 
    },
    sexualPreference: {
        type: String,
        required: true 
    },
    age: {
        type: Number,
        required: true 
    },
    description: {
        type: String,
        required: true 
    },
    pictures: {
        type: [{
            Object
        }],
    },
    matches: {
        type: [{
            Object
        }],
    },
})

module.exports = mongoose.model('User', userSchema);

只需将updateObject原样传递给findOneAndUpdate()函数，而不是将其包装在另一个对象中。

await User.findOneAndUpdate({ _id: new ObjectID(req.params.id) }, updateObject, //...)
