我有一个模型：

const comment = new mongoose.Schema({
  id: { type: ObjectId, required: true },
  comment: { type: String },
  replies: [comment]

            {

              "comment": "Child Comment",
              "replies": []
            }
          ]
        },
        {
          "id": 112,
          "comment": "Sibling Comment",
          "replies": []
        }
      ]
    }
