```

из-за того, что параметр пути `item_id` имеет значение `"foo"`, которое не является типом `int`.

Та же ошибка возникнет, если вместо `int` передать `float`, например: [http://127.0.0.1:8000/items/4.2](http://127.0.0.1:8000/items/4.2)

**FastAPI** обеспечивает валидацию данных, используя всё те же определения типов.
