  Verify Mapping:
  
  Check the external mapping configuration for the node. Ensure that the mapping is correctly set up and that it points to the correct input element.
  If necessary, update the mapping to reflect any changes made to the context structure.
  
  
  
  Review Changes:
  
  If the error occurred after recent changes, review those changes to identify any modifications that may have affected the input elements or the context structure.
  
  
  
  Test the Application:
