I am getting below error while processing data: [2020-05-28T11:35:29,467][WARN][org.logstash.instrument.metrics.gauge.LazyDelegatingGauge][main] A gauge metric of an unknown type (org.jruby.specialized.RubyArrayOneObject) has been created for key: cluster\_uuids. This may result in invalid serialization. It is recommended to log an issue to the responsible developer/development team. Logstash version: 7.7.0 My config file is- input{ file { path =\> "D:/ELK/529942\_1182360\_bundle\_archive/sars\_2003\_complete\_dataset\_clean.csv" sincedb\_path =\> "NUL" } } filter { csv { separator =\> "," columns =\> ["Date","Country","Cumulative number of case(s)","Number of deaths","Number recovered"] } } output{ elasticsearch{ hosts =\> "localhost:9200" index =\> "sarsindex" } ``` stdout {} ``` } If I have tried few solution from internet, but no luck. ---

That message has been occurring in the last few versions. I ignore it since it seems to do no harm. ---
