I'm very confused, that id absolute exists and is a Group. When I do a different relationship which is coded almost identically it has a different data structure for the id: 
   action_type: :create,
   action: :create_from_flow,
   attributes: %{},
   relationships: %{
     friend_one: [
       {[%{id: "266d68e7-3a8b-401a-a616-1b42c385a811"}],
   action_type: :create,
   action: :create_from_flow,
   attributes: %{},
   relationships: %{
     friend_one: [

what is the primary read action on the group resource?

xSHYNEOPā€¢2y ago
default 
  actions do
    defaults([:read, :update, :destroy])

    create :create do
      change relate_actor(:creator)
    end
  end
  actions do
    defaults([:read, :update, :destroy])

    create :create do

do you have relationships set with primary_key?: true on Group? or anything that could make that a composite primary key. in iex Ash.Resource.Info.primary_key(Group)
xSHYNE
xSHYNEOPā€¢2y ago
Ah I think I have two relationships 
Ash.Resource.Info.primary_key(Group)
[:id, :creator_id]
Ash.Resource.Info.primary_key(Group)
[:id, :creator_id]

ZachDanielā€¢2y ago
šŸ‘ thats the issue there šŸ™‚ Do you want that to be the primary key of that resource or was it an accident?
xSHYNE
xSHYNEOPā€¢2y ago
It looks like an accident but not sure how that happened Appreciate the quick help šŸ™‚
