I don’t like that we have those unused fields such as error, i18nMessagesMap, messages, etc. However, I do think the entity should be respected and used to return the appropriate payload; at least in that regard our endpoints are consistent.

By sending items outside of the entity, we open the door to more inconsistency and disorder. I would remove 'ok' and send items inside the entity, and then document that change properly.
