elasticsearch - 脚本参数不支持 : START_ARRAY in ElasticSearch v7. 类型的值 3 更新脚本

Question

我正在尝试为我的索引更新文档，并在通过 Postman 更新 API 脚本时收到以下错误

{
    "error": {
        "root_cause": [
            {
                "type": "x_content_parse_exception",
                "reason": "[5:15] [script] params doesn't support values of type: START_ARRAY"
            }
        ],
        "type": "x_content_parse_exception",
        "reason": "[5:15] [UpdateRequest] failed to parse field [script]",
        "caused_by": {
            "type": "x_content_parse_exception",
            "reason": "[5:15] [script] params doesn't support values of type: START_ARRAY"
        }
    },
    "status": 400
}

由于错误清楚地表明我正在更新文档中包含数据数组的字段。这是一个示例

"hasParts": [
    {
        "documentLevel": 2,
        "levelProperties": {
            //some properties
        }
    },
    {
        "documentLevel": 3,
        "levelProperties": {
            //some properties
        }
    },
    {
        "documentLevel": 3,
        "levelProperties": {
           //some properties
        }
    },
    {
        "documentLevel": 3,
        "levelProperties": {
            //some properties
        }
    }
]

我想使用更新 API 为文档之一更新上述属性。

这可能吗？如果可能，那么我做错了什么？
在此先感谢您的帮助。

这是脚本

{
  "script": {
    "source": "ctx._source.hasParts.add(params.haspart)",
    "lang": "painless",
    "params": [
      {
        "haspart": [
          {
            "documentLevel": 3,
            "levelProperties": {
              //some properties
            }
          },
          {
            "documentLevel": 3,
            "levelProperties": {
              //some properties
            }
          },
          {
            "documentLevel": 3,
            "levelProperties": {
              //some properties
            }
          },
          {
            "documentLevel": 3,
            "levelProperties": {
              //some properties
            }
          },
          {
            "documentLevel": 3,
            "levelProperties": {
              //some properties
            }
          }
        ]
      }
    ]
  }
}

您的 params部分不能是数组，而是对象，请改用此脚本:

{
  "script": {
    "source": "ctx._source.hasParts.add(params.haspart)",
    "lang": "painless",
    "params": {
        "haspart": [
          {
            "documentLevel": 3,
            "levelProperties": {
              //some properties
            }
          },
          {
            "documentLevel": 3,
            "levelProperties": {
              //some properties
            }
          },
          {
            "documentLevel": 3,
            "levelProperties": {
              //some properties
            }
          },
          {
            "documentLevel": 3,
            "levelProperties": {
              //some properties
            }
          },
          {
            "documentLevel": 3,
            "levelProperties": {
              //some properties
            }
          }
        ]
    }
  }
}
