我正在尝试运行此存储过程

DECLARE
  P_TICKER_SERIAL VARCHAR2(200);
  P_SECTOR_CODE   VARCHAR2(200);
  P_SOURCE_ID     VARCHAR2(200);
  P_COUNTRY_CODE  VARCHAR2(200);
  P_FILTER_TYPE   NUMBER;
  CUR_OUT         SYS_REFCURSOR;
  dbUserTable     DBUSER%ROWTYPE;
BEGIN
  P_TICKER_SERIAL :='14232';
  P_SECTOR_CODE   := '15';
  P_SOURCE_ID     := 'TDWL';
  P_COUNTRY_CODE  := 'SA';
  P_FILTER_TYPE   := 1;

  PKG_name.GET_user(
    P_TICKER_SERIAL => P_TICKER_SERIAL,
    P_SECTOR_CODE   => P_SECTOR_CODE,
    P_SOURCE_ID     => P_SOURCE_ID,
    P_COUNTRY_CODE  => P_COUNTRY_CODE,
    P_FILTER_TYPE   => P_FILTER_TYPE,
    CUR_OUT         => CUR_OUT
  );
  open CUR_OUT;
  LOOP
    FETCH CUR_OUT INTO dbUserTable;
    dbms_output.put_line(dbUserTable.email);
  END LOOP;
  CLOSE CUR_OUT;
END;
 /

但它给了我这个错误
