我正在尝试使用logstash及其配置将一些json数据导入elasticsearch和kibana集群。我使用的json文件有三个字段。

elasticsearch version used: 6.5.3
logstash version used: 6.5.3

使用的日志存储版本：6.5.3
示例json文件：test.json

{"name":"Jonathan","score":"9.9","address":"New Delhi"}
{"name":"Sam","score":"8.9","address":"New York"}
{"name":"Michelle","score":"9.0","address":"California"}

我的配置文件：test.config

input{
 file{
        path => "/Users/amit/elasticsearch/data/test.json"
        codec => json
        sincedb_path => "/dev/null"
        start_position => "beginning"
 }
}

filter{
    json{
        source => "message"
    }

    mutate{
        convert => { 
            "name" => "text"
            "score" => "float"
            "address" => "text"
        }
    }
}

output{
    elasticsearch{
        hosts => "localhost:9200"
        index => "test"
    }
    stdout { codec => rubydebug }
}

我正尝试使用以下命令使用logstash将此数据导入elasticsearch：

bin/logstash -f ../../data/test.config

但我得到以下错误信息：

另外，如果我从test.config文件中删除mutate过滤器，它也可以正常工作。但是，我想把score变量的类型改为float。在解析过程中尝试改变字段是否有问题，或者我遗漏了其他内容？谢谢：）
