尝试聚合时,"禁止加载字段数据"

Question

我正在尝试做一个简单的唯一聚合,但收到此错误:

java.lang.IllegalStateException: Field data loading is forbidden on eid

这是我的疑问:

                "field" : "eid"
              }
          }
        }

}

通过https://github.com/elastic/elasticsearch/issues/15267完成整个主题之后,添加了什么.

像这样:

"aggs": {
          "distinct_colors" : {
              "cardinality" : {
                "field" : "eid.raw"
              }
          }
        }
