Создайте собственный искатель с помощью spring

Я пытаюсь реализовать базу данных с отношением «многие ко многим». База данных построена, теперь нам нужны запросы к ней. Я использую эту статью в качестве примера: https://www.bezkoder.com/jpa-many-to-many/. Когда я создаю пользовательский поиск в репозитории - сервер зависает при запуске.

У меня есть две сущности: MassageEntity и RstringsEntity. Я пытаюсь создать метод List<MasageEntity> findMasageEntitiesByRstringsEntitiesId(Long string_id);. Без этого метода сервер запускается.

Вот как выглядит ошибка.

Не вижу смысла показывать контроллер, так как ошибка возникает в другом месте.

Что я делаю неправильно? Может быть, мне нужны какие-то настройки или зависимости? Или можно решить проблему другим способом?
