{
    "name": "Baz",
    "description": None,
    "price": 50.2,
    "tax": 10.5,
    "tags": []
}
```

FastAPI is smart enough (actually, Pydantic is smart enough) to realize that, even though `description`, `tax`, and `tags` have the same values as the defaults, they were set explicitly (instead of taken from the defaults).

So, they will be included in the JSON response.

     * For tests this must be big enough to realize real compression on test messages like

Si usas un bloque `try` en una dependencia con `yield`, recibirás cualquier excepción que se haya lanzado al usar la dependencia.

Por ejemplo, si algún código en algún punto intermedio, en otra dependencia o en una *path operation*, realiza un "rollback" en una transacción de base de datos o crea cualquier otro error, recibirás la excepción en tu dependencia.

Por lo tanto, puedes buscar esa excepción específica dentro de la dependencia con `except SomeException`.
