  Solution:
  
  Check Node ID Format: Verify that the Node ID being used is in the correct UUID format. If it is not, correct it to ensure it follows the standard UUID structure.
  Review Configuration: Check the configuration settings in the FDT or the application to ensure that the Node ID is correctly defined and referenced.
  Data Validation: If the Node ID is being generated dynamically, ensure that the logic for generating the UUID is functioning correctly and producing valid UUIDs.
  Recreate Node: If the Node ID is associated with a specific node in the FDT, consider recreating that node to ensure it has a valid UUID.
  Check for Updates: Ensure that your SAP system and components are up to date. Sometimes, applying the latest patches or updates can resolve such issues.
  Consult Documentation: Refer to SAP documentation or notes related to FDT and UUIDs for any specific guidelines or known issues.
