This typically occurs in scenarios where a system is undergoing maintenance or an upgrade, and certain functionalities are temporarily disabled to ensure data consistency and integrity.
  
  Cause:
  
  Ongoing ZDM Process: The primary cause of this error is that a ZDM process is actively running. During this time, certain functions may be restricted to prevent conflicts or data inconsistencies.
  Bridge System Configuration: The bridge system may not be fully configured or may be in a state that does not allow certain operations while the ZDM process is active.
