It appears you are using $service where you should have $cal.

so $calendarList = $service->calendarList->listCalendarList(); should be $calendarList = $cal->calendarList->listCalendarList();

and $calendarList = $service->calendarList->listCalendarList($optParams); should be $calendarList = $cal->calendarList->listCalendarList($optParams);
