This error typically occurs when there is an attempt to create a node in a hierarchy that already has a node with the same key or identifier.

  Use a Unique Key: If the key is already in use, consider using a different, unique key for the new node you are trying to add.
  Data Cleanup: If you suspect that there are inconsistencies or duplicates in your data, perform a cleanup of the hierarchy to remove or correct any duplicate entries.
  Hierarchy Maintenance: Review the hierarchy maintenance settings and ensure that the structure allows for the addition of new nodes without conflicts.
