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: <a href="http://127.0.0.1:8000/items/4.2" class="external-link" target="_blank">http://127.0.0.1:8000/items/4.2</a>

Isso seria útil se você deseja receber chaves que ainda não conhece.

Outro caso útil é quando você deseja ter chaves de outro tipo, por exemplo, `int`.

É isso que vamos ver aqui.

Neste caso, você aceitaria qualquer `dict`, desde que tenha chaves` int` com valores `float`:
