Ошибка обновления SELF_ATTENDEES_STATUS в таблице событий Google Calendar Android

Question

Я пытаюсь обновить SELF_ATTENDEES_STATUS в таблице событий следующим образом:

    private void UpdateCalendarEntry(int position, boolean isAccepted) {
        ContentResolver cr = mContext.getContentResolver();
        Uri updateUri = ContentUris.withAppendedId(CalendarContract.Events.CONTENT_URI, getEventId(mEvents.get(position).getTitle()));

        ContentValues values = new ContentValues();
        if(isAccepted) {
            values.put(CalendarContract.Events.SELF_ATTENDEE_STATUS, CalendarContract.Attendees.ATTENDEE_STATUS_ACCEPTED);
        } else {
            values.put(CalendarContract.Events.SELF_ATTENDEE_STATUS, CalendarContract.Attendees.ATTENDEE_STATUS_DECLINED);
        }

        cr.update(updateUri, values, null, null);
    }

Но, к сожалению, я получаю этот стек ошибок
