  Cause
  This error typically occurs during the execution of workflows or function modules when there is a mismatch or inconsistency in the expected parameter types. Specifically:
  
  The workflow container or function module expects parameters of certain data types.
  The actual parameters passed do not match the expected types (e.g., passing a string where an integer is expected).
  This type mismatch leads to a parameter type check failure.

  When calling function modules or methods with incorrect parameter types.
  After transport or upgrade where interface definitions have changed.
