Hi All, Good morning at the logstash logs I can see some warning message, since it is warning nothing wrong , but I am posting the message here for giving the feedback > 8.3.13:21374] Handling exception: org.logstash.beats.InvalidFrameProtocolException: Invalid version of beats protocol: 71 > [2019-10-30T04:27:21,311][WARN][io.netty.channel.DefaultChannelPipeline][main] An exceptionCaught() event was fired, and it reached at the tail of the pipeline.
