Hello Ahmed, Currently we only have 10 total Kafka request types, including produce request, fetch request and topic metadata request. And these requests are encoded with a key, currently ranging from 0 to 9. When Kafka server receives a request with key it cannot recognize, that exception will be thrown.
I am curious how a request with key 768 can be generated. Could you describe the process to reproduce it?
