Hi guys, we've just working on a PoC using permission on ORY network (I understands that underneath it's Keto). I've defined a permission rules like this

class User implements Namespace {
  related: {
    manager: User[]
  }
}

class Group implements Namespace {
  related: {
    members: (User | Group)[]
  }
}

class Folder implements Namespace {
  related: {
    parents: File[]
    viewers: SubjectSet<Group, "members">[]
  }

  permits = {
    view: (ctx: Context): boolean => this.related.viewers.includes(ctx.subject),
  }
}

class File implements Namespace {
  related: {
    parents: (File | Folder)[]
    viewers: (User | SubjectSet<Group, "members">)[]
    owners: (User | SubjectSet<Group, "members">)[]
    siblings: File[]
  }

  permits = {
    view: (ctx: Context): boolean =>
      this.related.parents.traverse((p) => p.related.viewers.includes(ctx.subject)) ||
      this.related.parents.traverse((p) => p.permits.view(ctx)) ||
      this.related.viewers.includes(ctx.subject) ||
      this.related.owners.includes(ctx.subject),

    edit: (ctx: Context) => this.related.owners.includes(ctx.subject),

    rename: (ctx: Context) => this.related.siblings.traverse((s) => s.permits.edit(ctx)),
  }
}

I've picked this directly from ORY example, I understands that with this configuration it'd means that to view File a subject can either be a a User or a members of a Group namespace. I've query the relationship like this

{
  "relation_tuples": [
    {
      "namespace": "Folder",
      "object": "AMC",
      "relation": "viewers",
      "subject_id": "group1"
    },
    {
      "namespace": "Group",
      "object": "group1",
      "relation": "members",
      "subject_id": "test1"
    },
    {
      "namespace": "File",
      "object": "file1",
      "relation": "parents",
      "subject_id": "AMC"
    }
  ],
  "next_page_token": ""
}

Now I've check the permission using REST call like this

{{ory_project}}/relation-tuples/check?namespace=File&object=file1&relation=viewers&subject_id=test1

it return a false. Am I missing something here? or I misunderstands some concept.
