elasticsearch groovy没有这样的属性:ctx for class

Question

这是我第一次在elasticsearch中使用脚本,我遇到了以下问题:

curl -XPOST 10.29.97.129:9200/.marvel-es-1-*/_search -d '{
          "query": {
            "bool": {
              "filter": [

                      "gte": "now-2m",
                      "lte": "now"
                    }
                  }
                },
                {
                  "terms": {
                    "cluster_state.status": ["green", "yellow", "red"]
                  }
                }
              ]
            }
          },
          "_source": [
            "cluster_state.status"
          ],
          "sort": [

                "order": "desc"
              }
            }
          ],
          "size": 1,
          "aggs": {
            "minutes": {

                    "size": 3
                  }
                }
              }
            }
          },
          "script_fields" : {
            "aggregationstest" : {
              "script": "return ctx.payload"
            }
          }   
 }'

据我所知,ctx是groovy默认的context,任何人都可以给我一些提示？
