Pero declarar el tipo es recomendable, ya que de esa manera tu editor sabrá lo que se pasará como el parámetro `commons`, y entonces podrá ayudarte con el autocompletado, chequeo de tipos, etc:

Pero ves que estamos teniendo algo de repetición de código aquí, escribiendo `CommonQueryParams` dos veces:

 * {@link #enqueue} and {@link #dispatch} are 2 different methods. It is expected that the decision
 * to run a particular event is made during the state change, but the decision to actually invoke
 * the listeners can be delayed slightly so that locks can be dropped. Also, because {@link
 * #dispatch} is expected to be called concurrently, it is idempotent.

Revisa esta función, ya tiene anotaciones de tipos:

Porque el editor conoce los tipos de las variables, no solo obtienes autocompletado, también obtienes chequeo de errores:

Ahora sabes que debes corregirlo, convertir `age` a un string con `str(age)`:
