Filebeat 7.17.2 not sending logs to kibana

Hi Team,

I have upgraded filebeat from 5.6.5 to 7.17.2 in windows machine. Filebeat is running fine after upgrade but it is not sending logs to Kibana. When I reverted changes back to 5.6.5 , logs are coming to kibana so could you please help me in finding root cause why after upgrade logs are not going to kibana.

Below is the error in logstash logs when using 7.17.2 version.

{"level":"WARN","loggerName":"io.netty.channel.DefaultChannelPipeline","timeMillis":1651135560399,"thread":"nioEventLoopGroup-12-4","logEvent":{"message":"An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception."}}

Thanks and Regards,
Naman

Also my logstash version is 7.9.3 so will it create conflict?

Could any one please respond?

It'd be useful if you shared your various configs, as well as the Filebeat logs.
