javascript - 调用方法失败

Question

我们有这个 MongoDB Mongoose 查询:

sampleSchema.find({
    $where: "expired <= " + (new Date())
  })
  .limit(9)
  .sort({
    postedDate: -1
  })
  .then((docs) => {
    console.log('found docs ', docs);
  })
  .catch((err) => {
    console.log('error ', err);
  })

此查询始终转到 catch block ，抛出的错误是:

{
  "name": "MongoError",
  "message": "Failed to call method",
  "ok": 0,
  "errmsg": "Failed to call method",
  "code": 1,
  "codeName": "InternalError"
}

此查询有什么问题？

这成功了:

{expire: {$lte : (new Date())}
