Will you post the configuration of the GenerateFlowFile processor?
Are you seeing the same error now?

What does the config of the PublishKafka processor look like?

So, there is a Kafka Broker running on the same system as NiFi?
Is this an HDF cluster?
Is 9092 the correct port?

Thanks for the response @Wynner
Yes this is a kafka broker running on the same system.
No it is not a HDF cluster
yes 9092 is the correct port
Thanks

Try putting the actual host name instead of localhost for the Kafka Broker property.

Thanks a lot for your patience.
I did try putting in the hostname instead of IP address but no success
