以下是 CURL 测试我方服务器是否正确处理接口响应的代码：

curl -X POST https://yudingai.com/wechatcallback \

  -H "Content-Type: application/json" \

  -d '{

    "ToUserName": "gh_9df7d78a1234",

    "FromUserName": "o4_t144jTUSEoxydysUA2E234_tc",

    "CreateTime": 1626959646,

    "MsgType": "event",

    "Event": "wxa_media_check",

    "appid": "wx8f16a5be77871234",

    "trace_id": "60f96f1d-3845297a-1976a3ae",

    "version": 2,

    "detail": [{

      "strategy": "content_model",

      "errcode": 0,

      "suggest": "pass",

      "label": 100,

      "prob": 90

    }],

    "errcode": 0,

    "errmsg": "ok",

    "result": {

      "suggest": "pass",

      "label": 100

    }

  }'

因为选择是的明文模式，所以返回的是 success；

麻烦帮忙检查一下这个 trace_id:68495839-7e5f4458-02d7c64a，我方服务器并未接收到异步的检测结果回调，请问是什么原因呢？
