我正在尝试使用 circle 将圆转换为多边形的处理器，因为 circle geo_shape 正在弃用，请遵循以下文档：
https://www.elastic.co/guide/en/elasticsearch/reference/7.4/ingest-circle-processor.html#_example_circle_defined_in_geojson
但是，当我在我的amazon elasticsearch 7.7示例上运行它时，会出现以下错误：

{
   "error":{
      "processor_type":"circle",
      "reason":"No processor type exists with name [circle]",
      "root_cause":[
         {
            "processor_type":"'circle'",
            "reason":"'No processor type exists with name [circle]'",
            "suppressed":"[{'type': 'parse_exception', 'reason': 'No processor type exists with name [circle]', 'processor_type': 'circle'}]",
            "type":"'parse_exception'"
         }
      ],
      "suppressed":[
         {
            "processor_type":"'circle'",
            "reason":"'No processor type exists with name [circle]'",
            "type":"'parse_exception'"
         }
      ],
      "type":"parse_exception"
   },
   "status":400
}

据我所知 circle 处理器从7.4版开始提供。
这是已知的问题吗？有没有办法将此处理器添加到aws的elasticsearch中？
