  The SAP error message FDT_EXPRESSIONS345 indicates that there is an issue with the end node ID of a connector in a flow or expression within the SAP system. Specifically, it states that the end node ID is not a valid UUID (Universally Unique Identifier). This error typically arises in the context of SAP Fiori or SAP UI5 applications, particularly when dealing with expressions or data flows in the FDT (Form Data Tool) or similar frameworks.
  Cause:
  
  Invalid Node ID: The end node ID specified in the connector does not conform to the UUID format. A valid UUID is a 128-bit number represented as a string of hexadecimal digits, typically displayed in five groups separated by hyphens (e.g., 123e4567-e89b-12d3-a456-426614174000).
  Configuration Issues: There may be a misconfiguration in the flow or expression where the connector is defined, leading to an incorrect or missing node ID.
  Data Corruption: The data model or configuration might be corrupted, leading to invalid references.
  Version Compatibility: There may be compatibility issues between different versions of the software or components being used.
  
  Solution:
  
  Check Node ID: Verify the end node ID specified in the connector. Ensure that it is a valid UUID. If it is not, correct it to a valid UUID format.
  Review Configuration: Go through the configuration of the flow or expression where the error occurs. Ensure that all connectors and nodes are correctly defined and that there are no missing or incorrect references.
