ORA-37158: Bad clob or varray IN-args: (case [string])
Cause: When in clob or varray mode, the PL/SQL mappings of OLAP API''s IDL interface methods were executed blindly with null clob/varray or non-null clob/varray containing garbages.
Action: Do not blindly execute them as doing so does not make sense unless you understand how OLAP API works internally.
Error Type: ORA
