使用弹性座垫和角度4出现“无法找到geo_point字段[pin.location]”错误

Question

当我尝试使用Angular 4调用弹性搜索API时，我遇到此错误，无法使用弹性座垫和角度4来找到geo_point字段[pin.location]错误

我的Angular代码   fullTextSearch（_index，_type，_field，_queryText）：任意{

return this.client.search({
  index: _index,
  body: {
    "query": {
        "bool" : {
            "must" : {
                "match_all" : {}
            },
            "filter" : {
              "geo_distance" : {
                    "distance" : "150km",
                    "location" : {
                      "lat" : -70.34,
                      "lon" : 40.12 
                    }
                }
            }
        }
    }
}
});

}

我的elasticsearch _search API数据

                    }
                }
            },
            {
                "_index": "dev_ll_user",
                "_type": "user",
                "_id": "12f7b1c5-2f2d-4841-a8ba-9bc46de3f73f",

                    }
                }
            }
        ]
    }
}

我收到此错误
