  Incorrect Node Type: The node you are trying to access or use is not configured as a gateway node. This could happen if the node was incorrectly defined in the FDT configuration.
  Misconfiguration: There may be a misconfiguration in the data model or the transformation logic that leads to the system expecting a gateway node but finding a different type.

  Correct Node Type: If the node is not supposed to be a gateway node, update your transformation logic to use the correct node type that matches your requirements.
  Review Data Model: Ensure that the data model you are working with is correctly set up and that all nodes are properly defined according to their intended roles.
  Consult Documentation: Refer to the SAP documentation for the FDT framework to understand the requirements for node types and how to configure them correctly.
