Steps to Reproduce

  1. Create a service rule. The service must open existing work objects and update them with the details received in the Service request
  2. Queue this request if the Service requestor is unable to lock the work object.
  3. Create a System-Queue-ExecutionRequest-Service-Default instance. This is the out-of-the-box feature available to handle Service requests. The queue item created in Step 3 is in the Broken status with 'Database rollback caused queue item rollback' exception.

Root Cause

A defect in Pegasystems’ code or rules.
BatchRequestorTask does not display the error message when the service activity fails. It displays a generic error message in all error scenarios.
