Isso também funcionará porque `RedirectResponse` é uma subclasse de `Response`, e o FastAPI tratará automaticamente este caso simples.

### Anotações de Tipo de Retorno Inválido

Mas quando você retorna algum outro objeto arbitrário que não é um tipo Pydantic válido (por exemplo, um objeto de banco de dados) e você o anota dessa forma na função, o FastAPI tentará criar um modelo de resposta Pydantic a partir dessa anotação de tipo e falhará.

     * <p>{@code [<E>]} will be returned for ArrayList's constructor. When both the class and the

     * the other. From the declaration syntax, the class type parameter appears first, but the call
     * syntax may show up in opposite order such as {@code new <A>Foo<B>()}.

### Invalid Return Type Annotations { #invalid-return-type-annotations }

But when you return some other arbitrary object that is not a valid Pydantic type (e.g. a database object) and you annotate it like that in the function, FastAPI will try to create a Pydantic response model from that type annotation, and will fail.

        // fill in the rest of the array with arbitrary instances
        for (int i = 2; i < params.length; i++) {
          params[i] = ArbitraryInstances.get(sig.get(i));
        }
      }
    }
    return params;
