Karena parameter path `item_id` bernilai `"foo"` yang bukan tipe data `int`.

    * Jika tidak, klien akan melihat pesan kesalahan jelas.
* Periksa jika ada parameter *query* opsional bernama `q` (seperti `http://127.0.0.1:8000/items/foo?q=somequery`) untuk permintaan `GET`.
    * Karena parameter `q` dideklarasikan dengan `= None`, maka bersifat opsional.
    * Tanpa `None` maka akan menjadi wajib ada (seperti struktur di kondisi dengan `PUT`).
