Hi I am trying to explore KoP on pulsar, I have made the config changes following the documentation, but when I am trying to produce to the topics(created from pulsar-admin tool) I am getting the following exception in kafka client

WARN [Producer clientId=console-producer] Bootstrap broker <ip>:9092 (id: -1 rack: null) disconnected (org.apache.kafka.clients.NetworkClient)

Logs from broker don't have much info and all I can see is this

13:09:21.931 [pulsar-io-4-2] DEBUG io.streamnative.pulsar.handlers.kop.KafkaCommandDecoder - [/<ip>:42816] Received kafka cmd RequestHeader(apiKey=API_VERSIONS, apiVersion=3, clientId=console-producer, correlationId=23), the request content is: KafkaHeaderAndRequest(header=RequestHeader(apiKey=API_VERSIONS, apiVersion=3, clientId=console-producer, correlationId=23), request={}, remoteAddress=/<ip>:42816)

command used to produce

./bin/kafka-console-producer.sh --topic viesti/ns1/k1 --bootstrap-server <ip>:9092

pulsar and kop version used: 2.9.3.19, kafka_client version:

kafka_2.12-2.8.2 and kafka_2.13-3.3.1

Tried both versions and none of them worked. Anyone else has seen similar issues?
