Salesforce Connector Replay Channel Listener – ReplayId Persistence Fails Due to Orphaned _BACKUP Key in Object Store V2 (CloudHub 1.0)

The Salesforce Connector Replay Channel Listener persists ReplayIds to Object Store V2 to ensure that Platform Event consumption resumes from the correct position after a restart or reconnect.

During ReplayId persistence, the connector temporarily creates a backup entry (<ReplayKey>_BACKUP) as part of its update process. If the worker is terminated unexpectedly or multiple workers overlap during deployment, this backup entry may not be removed.

On the next persistence attempt, Object Store V2 detects that the backup key already exists and throws the following exception:

ObjectAlreadyExistsException: Object already exists for key <ReplayKey>_BACKUP

As a consequence:

• ReplayId persistence fails.
• The connector continues processing Platform Events using the in-memory ReplayId.
• The ReplayId stored in Object Store remains unchanged.
• After an application restart or reconnect, the connector resumes from the stale ReplayId, which can result in duplicate Platform Events being delivered.
