```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null
    }
  ]
}
```

Como `needy` es un parámetro requerido, necesitarías establecerlo en la URL:

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

...esto funcionaría:
