Mongoose从6.7.2升级至7.0.3后控制器函数异常无报错

问题背景 #

项目使用Mongoose作为ODM，Express后端将Mongoose从6.7.2版本升级至7.0.3后，下述控制器函数出现异常，但无法定位具体原因。

导入配置 #

import asyncHandler from 'express-async-handler'
import Intervention from '../models/intervention.model.js'
import mongoose from 'mongoose'

出现异常的控制器函数 #

// @desc    获取单个干预记录
// @route   GET /api/interventions/:id
// @access  受保护
const getInterventionById = asyncHandler(async (req, res) => {
  const oid = new mongoose.Types.ObjectId(req.params.id)
  const pipeline = [
    {
      $match: {
        _id: oid,
      },
    },
    {
      $lookup: {
        from: 'students',
        localField: 'student_id',
        foreignField: '_id',
        as: 'student',
      },
    },
    {
      $unwind: {
        path: '$student',
      },
    },
    {
      $lookup: {
        from: 'campuses',
        localField: 'student.campus_id',
        foreignField: '_id',
        as: 'campus',
      },
    },
    {
      $unwind: {
        path: '$campus',
      },
    },
  ]

  try {
    const results = await Intervention.aggregate(pipeline)
    console.log(results)
    return res.json(results)
  } catch (error) {
    console.log(error)
    throw new Error(error.message)
  }
})

已做排查 #

• 已添加日志输出，但未捕获到任何报错信息
• 查阅Mongoose官方迁移指南，未找到与该问题相关的变更内容
