Mongoose 中的日期范围查询 将循环结构转换为 JSON

Question

转换为momentJS然后在数据库中搜索后，我遇到了这个问题。 它在 catch 块中向我显示以下错误

将循环结构转换为 JSON\n --> 从 object 开始，使用构造函数 'NativeTopology'\n | 属性 's' -> object 与构造函数 'Object'\n | 属性 'sessionPool' -> object 和构造函数 'ServerSessionPool'\n --- 属性 'topology' 关闭圆圈

const getAppointmentByDate = async(req, res, next) => {
  try {
    //get dates from req.query by es6 object destructuring
 
 
   //1. check that date is not empty
 
   //2. check that date is in the right format
  //expected result: YYY-MMM-DDD

    reqDate = new Date("1-1-2021")

    var today = moment(new Date()).format('YYYY-MM-DD[T00:00:00.000Z]');
    console.log("Next day -- " + (reqDate.getDate() + 1))
    var d = new Date();
    d.setDate(reqDate.getDate() + 1);
    var tomorrow = moment(d).format('YYYY-MM-DD[T00:00:00.000Z]');
 
 //In some cases you'll get a date-time format where you have to separate the date
 //from the time.
 
  const transactions = Appointment.find({  
    "schedule_datetime": {
      "$gte": new Date(today),
      "$lt": new Date(tomorrow)
    }
  })

 //4. Handle responses
 if(!transactions) {
 return res.status(404).json({
  status:'failure',
  message:'Could not retrieve transactions'
 })
 }
 
 
 res.status(200).json({
 status:'success',
 data: transactions
    })
 
 } catch(error) {
   return res.status(500).json({
      status:'failure',
      error: error.message
         })
  }

  }
