API: Type entities for actor types
The endpoint /type_entities will throw an 'No entity exist for this category.' error for "Actor actor relation", "Actor function" and "Involvement". The cause for this is that the attached entities are connected via a link. The actors are in the UI separated in Domain and Range.
One solution would be, that no matter if the actor is in range or domain, it will be selected for the endpoint, because the relation information is included at the entity itself.
Maybe we need to discuss this furthermore, or I just implement it as stated.
Thank you Christoph for reporting.
