While reading from a test topic in a local wurstmeister/kafka docker container:

Seems to be an issue in the underlying sarama library, but was fixed last year: IBM/sarama#1149

I'm using Kafka 2.12-2.1.0 and the latest kt release. I note that your latest release is significantly earlier than the bugfix in sarama, so probably just requires a sarama upgrade.

Actually I notice that d9ec6d updates sarama, so I think it's just a lack of a release that's the problem. I'll close this and raise a separate issue.
