我正在使用kibana6.8中的开发工具通过查询删除文档，但是我收到了一个403，类型是“cluster_block_exception”，原因是“blocked by:[forbidden/8/index write（api）]；”。
我使用了以下命令：

curl -XPOST "http://localhost:9200/my_index/_delete_by_query" -H 'Content-Type: application/json' -d'
{
  "query": {
    "match_all": {}
  }
}'

下面是一个示例响应：

  "timed_out": false,
  "total": 2,
  "deleted": 0,

  "version_conflicts": 0,

      "cause": {
        "type": "cluster_block_exception",
        "reason": "blocked by: [FORBIDDEN/8/index write (api)];"
      },
      "status": 403
    },
    {
      "index": "my_index",
      "type": "doc",
      "id": "T3OKCHMBlyetxY-P6XYF",
      "cause": {
        "type": "cluster_block_exception",
        "reason": "blocked by: [FORBIDDEN/8/index write (api)];"
      },
      "status": 403
    }
  ]
}

任何关于如何设置适当权限的帮助都将不胜感激。谢谢。
