  Cause:
  This error generally indicates that the system is unable to determine the cardinality of the data model or the relationships between different entities in the system. Cardinality refers to the uniqueness of data values contained in a particular attribute (or column) of a database table. The error can arise due to:
  
  Incomplete Configuration: The system may not have been fully configured to understand the relationships between different data entities.
  Missing Data: There may be missing or incomplete data in the source system that prevents the determination of cardinality.
  Incorrect Mapping: The mapping of source and target fields may not be correctly defined, leading to ambiguity in data relationships.
