  The system is trying to reverse an allocation that was never completed or was already canceled.
  
  
  
  Data Integrity Issues: There may be issues with the data integrity in the system, such as missing or incorrect entries in the database that lead to inconsistencies in the allocation records.

  Solution:
  
  
  Check Allocation Status: Verify the status of the container and object allocations. Ensure that the allocation you are trying to reverse is in a state that allows for reversal. If it has already been confirmed or processed, you may need to follow a different procedure.
