lucasbru opened a new pull request, #15419: URL: https://github.com/apache/kafka/pull/15419
The group coordinator expects the instance ID to always be sent when leaving the group in a static membership configuration, see https://github.com/apache/kafka/blob/ea9450767932eb3d63aeefd5af07dbc54cb92c31/group-coordinator/src/main/java/org/apache/kafka/coordinator/group/GroupMetadataManager.java#L814 The failure was silent, because the group coordinator does not log failed requests and the consumer doesn't wait for the heartbeat response during close. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
