Estoy intentando buscar una ubicacion haciendo uso de la clase Id de pyson de la siguiente manera:
```auto
@staticmethod
def default_warehouse():
Location = Pool().get('stock.location')
location, = Location.search(
[('id', '=', Id('stock', 'location_warehouse'))])
return location.id
```
Pero obtengo el siguiente error:
```auto

You can not use PYSON statement directly in the `domain` of `ModelStorage.search`.
You must retrieve the id of the location using `ModelData.get_id` (`ir.model.data`).
