  Cause:
  
  Naming Convention Issues: The internal name of an InfoObject or field does not conform to the expected naming conventions or contains invalid characters.
  Data Source Mismatch: There may be a mismatch between the internal representation of a data source and its external representation, possibly due to changes in the data model or InfoObjects.
