Это потому, что по умолчанию FastAPI проверяет каждый элемент внутри и убеждается, что он сериализуем в JSON, используя тот же [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}, объяснённый в руководстве. Это позволяет возвращать **произвольные объекты**, например модели из базы данных.
