现在试着发送一个无效的 `item`，例如：

```JSON
{
  "title": "towel",
  "size": "XL"
}
```

收到的响应会告诉你数据无效，并包含收到的请求体：

```JSON hl_lines="12-15"
{
  "detail": [
    {
      "loc": [
        "body",
        "size"
      ],
      "msg": "value is not a valid integer",
      "type": "type_error.integer"
    }
  ],
  "body": {
    "title": "towel",
    "size": "XL"
  }
}
```

### `///` admonitions

- Keep the admonition keyword in English (do not translate `note`, `tip`, etc.).
- If a title is present, prefer these canonical titles (choose one canonical form where variants exist):

- `/// note | Примітка`
- `/// note | Технічні деталі`
- `/// tip | Порада`
- `/// warning | Попередження`

Y guardará el valor devuelto en un <dfn title="Una utilidad/sistema para almacenar valores calculados/generados, para reutilizarlos en lugar de calcularlos nuevamente.">"caché"</dfn> y lo pasará a todos los "dependants" que lo necesiten en ese request específico, en lugar de llamar a la dependencia...
