**Describe the bug** Whenever replication is enabled between two clusters, we come across the following error messages: ``` 17:09:22.536 [bookkeeper-ml-workers-OrderedExecutor-3-0] ERROR org.apache.pulsar.broker.service.persistent.PersistentReplicator - [persistent://xxx/xxx/default-partition-1][xxxA -> xxxB] Unexpected exception: null ``` - The messages appear every couple seconds - The messages appear on both ends - The replication appears to be operating properly - Replication was enabled and disabled a couple of times with no meaningful progress, the error keeps appearing. - There's no stack trace occuring with the message **To Reproduce** Steps to reproduce the behavior: - Unclear how to reproduce the issue, it appears on a specific pair of clusters. **Expected behavior** - No error messages **Screenshots** If applicable, add screenshots to help explain your problem. **Desktop (please complete the following information):** - Pulsar 2.6.1 - Kubernetes - AWS environment on both ends **Additional context** We're not clear if this is causing any actual issue, the exception happens in this block https://github.com/apache/pulsar/blob/v2.6.1/pulsar-broker/src/main/java/org/apache/pulsar/broker/service/persistent/PersistentReplicator.java#L332 but we're not sure exactly which code line is causing this.
