ERROR Error when sending message to topic

Question

While producing message in kafka, i am getting the following error :

$ bin/kafka-console-producer.sh --broker-list localhost:9092 --topic nil_PF1_P1
hi
hello         


        

Answer 1

adding such a line after the topic helped with the same issue: ... --topic XXX --property "parse.key = true" --property "key.separator =:"

Hope this helps someone.
