Exactly same issue for me.

Exact same thing is happening to me: { "errors" : [ { "id" : "<id>", "status" : "409", "code" : "ENTITY_ERROR.RELATIONSHIP.INVALID", "title" : "The provided entity includes a relationship with an invalid value", "detail" : "You cannot create a new version of the App in the current state.", "source" : { "pointer" : "/data/relationships/app" } } ] }
