I Am getting below error as soon as I create new pipeline. This happens befog i add stages and rules to the pipeline. Same error repeats after attaching stream to it.
2018-01-24T04:41:46.920Z WARN [DeadEventLoggingListener] Received unhandled event of type <org.graylog.plugins.pipelineprocessor.processors.PipelineInterpreter.State> from event bus <AsyncEventBus{graylog-eventbus}>
But problem what I am facing is, even after attaching a stream to the pipeline, no messages is flowing into pipeline. So i am concerned if this warning is causing any problem.
