假设我有这个文档结构：

{
     "_id": <ObjectId goes here>,
     "postBody": "test",
     "photos": [
          {"url": "url1.com", "status": 0},
          {"url": "url2.com", "status": 0},
          {"url": "url3.com", "status": 0},
          {"url": "url4.com", "status": 0}
     ]
}

我有这个要删除的网址列表

toDelete = ["url2.com", "url3.com"]

如何在 mongo 查询中执行此操作？

这是我到目前为止尝试过的

db.Post.update_one(
     {"_id": <ObjectId goes here>},
     {
          "$pull": {
               "photos": {
                    "url": {
                         "$in": toDelete
                    }
               }
          }
     }
)

但不知何故，它不起作用。我该怎么做？

更新后的文档应该看起来像这样

{
     "_id": <ObjectId goes here>,
     "postBody": "test",
     "photos": [
          {"url": "url1.com", "status": 0},
          {"url": "url4.com", "status": 0}
     ]
}

我需要帮助。

更新：我收到此错误
