devido ao parâmetro da rota `item_id` ter um valor `"foo"`, que não é um `int`.

O mesmo erro apareceria se você tivesse fornecido um `float` ao invés de um `int`, como em: <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>

	Então, com a mesma declaração de tipo do Python, o **FastAPI** dá pra você validação de dados.

        return buf;
    }

    @Test
    @DisplayName("constructor initialises command and parameters correctly")
    void testConstructorInitialisesFields() throws Exception {
        int level = 42;
        Trans2QueryFSInformation cmd = new Trans2QueryFSInformation(level);
        // constants are defined on SmbComTransaction, inherited via
        // ServerMessageBlock.

Die gleiche Fehlermeldung würde angezeigt werden, wenn Sie ein `float` (also eine Kommazahl) statt eines `int`s übergeben würden, wie etwa in: <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>

Sprich, mit der gleichen Python-Typdeklaration gibt Ihnen **FastAPI** Datenvalidierung.
