> The new group coordinator always expects the leader epoch to be received when
> it must unload the metadata for a partition. However, in KRaft, the leader
> epoch is not passed when the replica is delete (e.g. after reassignment).
> {noformat}
> java.lang.IllegalArgumentException: The leader epoch should always be
> provided in KRaft.
