我想在kibana的Map上表示一条线，Map应该是geojson结构。我拥有的数据是一组sql表，然后我将使用如下的logstash将它们传输到ElasticSearch

input{ ... }

filter{

 if [lat] and [lon] {
        mutate{convert =>  ["lat", "float"]}
        mutate{convert =>  ["lon", "float"]}
        mutate{convert =>  ["for_lat", "float"]}
        mutate{convert =>  ["for_lon", "float"]}

        mutate{
            add_field => {"[location-geotest][type]" => "multilinestring"}
            add_field => {"[location-geotest][coordinates]" => [["%{lon}", "%{lat}"]]}
            add_field => {"[location-geotest][coordinates]" => [["%{for_lon}", "%{for_lat}"]]}
            }
      }
}

但是，logstash conf文件未能索引elasticsearch上的数据

{
    :status=>400, 
    :action=>["index", {:_id=>"18022", :_index=>"geo_shape_test", :routing=>nil, :_type=>"_doc"}, #<LogStash::Event:0x687994b9>], 
    :response=> {
        "index"=>{
            "_index"=>"geo_shape_test", 
            "_type"=>"_doc", 
            "_id"=>"18022", 
            "status"=>400, 
            "error"=>{
                "type"=>"mapper_parsing_exception", 
                "reason"=>"failed to parse field [location-geotest] of type [geo_shape]", 
                "caused_by"=>{"type"=>"x_content_parse_exception", 
                    "reason"=>"[1:164] [geojson] failed to parse field [coordinates]", 
                    "caused_by"=>{
                        "type"=>"parse_exception", 
                        "reason"=>"geo coordinates must be numbers"
                    }
                }
            }
        }
    }
}

这是logstash试图索引的内容之一

{
                 "lat" => 37.567179953757886,
              "gps_id" => 10491,
           "timestamp" => 2020-11-22T06:10:45.000Z,
               "speed" => 17.25745240090587,
                 "lon" => 126.99598717854032,
             "for_lat" => 37.567179953757886,
          "@timestamp" => 2020-11-27T03:54:21.131Z,
             "for_lon" => 126.99598717854032,
            "@version" => "1",
    "location-geotest" => {
        "coordinates" => [
            [0] "[\"126.99598717854032\", \"37.567179953757886\"]",
            [1] "[\"126.99598717854032\", \"37.567179953757886\"]"
        ],
               "type" => "multilinestring"
    }
}

我想问题是。。。

"coordinates" => [
            [0] "[\"126.99598717854032\", \"37.567179953757886\"]",
            [1] "[\"126.99598717854032\", \"37.567179953757886\"]"
        ],

如果我换一个角色，它会是。。。

"coordinates" => [
            [0] [126.99598717854032, 37.567179953757886],
            [1] [126.99598717854032, 37.567179953757886]
        ],

但我找不到解决方法。
