Почему там ошибка?

Вы получили исключение нулевого указателя в вашем createPopUpMenuScene метод. Номер строки, генерирующей это исключение, - 285. В любом случае, потому что я не могу определить 285-ю строчку, на которые вы разместили строки, поэтому я не могу дать вам четкий и прямой ответ.
По моему мнению, такие проблемы можно легко решить, пройдя по строкам кода путем отладки приложения.
