This error indicates that there is an issue with the mapping of parameters, specifically that the move type of the source and target fields is incompatible.
  
  Cause:
  The error arises when:
  
  Incompatible Data Types: The source and target fields have incompatible data types. For example, trying to map a string to a numeric field without proper conversion.
  Incorrect Mapping Configuration: The mapping configuration may not align with the expected data types or structures.
  Move Type Issues: The move type defined for the mapping does not match the expected move type for the target field. For instance, if the target field expects a certain type of input (like a single value) but the source provides a different type (like a list or array).
