Update chatroom affiliations returns bad request

[nereglez]

Hello there,

We are using the rest api plugin and we are trying to set affiliations at a chatroom but the PUT endpoint (restapi/v1/chatrooms/{roomName}/{affiliation: (admins|members|outcasts|owners)}) returns a bad request response when we send an array of usernames:

Seems that it's necessary indicate how to distinguish what child class of AffiliatedEntities has to be created.
Thanks in advance
