This typically occurs when the metadata of the CDS view has been modified, which can affect how the view is consumed in other parts of the system, such as in reports, queries, or other CDS views.
  Cause:
  The error is triggered when:
  
  The external name of a field in a CDS view has been changed (e.g., during a development or transport process).
