当响应序列化时，BucketAggregate 上的“键”丢失

如何解决当响应序列化时，BucketAggregate 上的“键”丢失

我正在将服务从 ES 5.0 升级到 6.8。我有一个在 v5 中序列化的存储桶聚合：

      "items": [
        {
          "key": "random+topic","docCount": 27919,"aggregations": {
            "ParentReference": {
              "docCount": 24992,"aggregations": {
                "Popularity": {
                  "value": 25223
                }
              }
            }
          }
        },{
          "key": "unkNown problem+latency","docCount": 24566,"aggregations": {
            "ParentReference": {
              "docCount": 23419,"aggregations": {
                "Popularity": {
                  "value": 23931
                }
              }
            }
          }
        },

使用 Elasticsearch.Net 和 nest 的 v6，序列化后，我最终得到：

      "items": [
        {
          "ParentReference": {
            "Popularity": {
              "value": 25223
            }
          }
        },{
          "ParentReference": {
            "Popularity": {
              "value": 23931
            }
          }
        },

我之前遇到过不再返回“聚合”属性的问题（尽管我希望有一个指向有关重大更改公告的指针），并相应地更新了我的代码。但是，如果没有 Key 和 docCount，我将无能为力。我想一定有一些与 Json 解析更改相关的东西。

我已经尝试过以下步骤： Custom Serialization | Elasticsearch.Net and NEST: the .NET clients [6.x] | Elastic

我尝试过使用默认序列化器，以及使用 JsonNetSerializer 的自定义序列化器。默认无效。

谁能就我应该做什么提出建议？

请注意，这是我获取 BucketAggregate 的方式：

        var childAgg = response.Aggregations[ss.Type] as SingleBucketAggregate;
        var nestedAgg = childAgg.Aggregations[ss.Path] as SingleBucketAggregate;
        var countAgg = nestedAgg.Aggregations[sstermsName] as BucketAggregate;
        return new ProviderResult<BucketAggregate>
        {
            Result = countAgg,};

谢谢！ ~约翰

附加：

Elasticclient elasticclient_BuiltInSerializer = new Elasticclient(); var source = elasticclient_BuiltInSerializer.sourceSerializer.SerializetoString(o); var response = elasticclient_BuiltInSerializer.RequestResponseSerializer.SerializetoString(o);

            ConnectionSettings connectionSettings = new ConnectionSettings(new SingleNodeConnectionPool(new Uri("http://fake")),JsonNetSerializer.Default);
            Elasticclient elasticclient_JsonNetSerializer = new Elasticclient(connectionSettings);

            var source2 = elasticclient_JsonNetSerializer.sourceSerializer.SerializetoString(o);
            var response2 = elasticclient_JsonNetSerializer.RequestResponseSerializer.SerializetoString(o);
