Kafka Version
2.4.1

To Reproduce
No idea how to reproduce.

Expected behavior
be able to fetch message

Additional context
compact topic, messages have no headers at all (headers not set) produced by Java application using official Kafka client libs (same version as kafka cluster).

In order to debug this further, we would need some more information. If the exact root cause is not yet known, some more information about your Kafka environment and what kafka-go APIs you are using (eg: reader? consumer groups?)

It's also been a while since reported, so perhaps updating to the latest version of the API (0.4) would also be helpful. Feel free to re-open the ticket if you can provide more details for us to help diagnose with.
