Kafka not consuming messages

I've run the following steps, but there is no data in my target table, or error in the log:

/opt/vertica/packages/kafka/bin/vkconfig scheduler --add —-username dbadmin —-password pass

CREATE FLEX TABLE public.kafka_tgt();

/opt/vertica/packages/kafka/bin/vkconfig topic --add --target public.kafka_tgt --rejection-table public.kafka_rej --topic testiaTest --num-partitions 1 --username dbadmin --password pass

/opt/vertica/packages/kafka/bin/vkconfig kafka-cluster --add --brokers (IP HERE):9092 --cluster K_cluster_1 --username dbadmin --password pass

/opt/vertica/packages/kafka/bin/vkconfig launch --conf /home/dbadmin/config.properties

Any ideas how to debug this?

thanks
