Como neste caso (sem usar `Annotated`) temos que substituir o valor padrão `None` na função por `Query()`, agora precisamos definir o valor padrão com o parâmetro `Query(default=None)`, ele serve ao mesmo propósito de definir esse valor padrão (pelo menos para o FastAPI).

Então:

```Python
q: str | None = Query(default=None)
```

		// in a federated setup cannot be proxied, so serve them at

		if bucket == "" {
			h.ServeHTTP(w, r)
			return
		}
