I have a an action:

    read :by_domain do
      primary? false

      argument :domain, :string, allow_nil?: false

      get? true

      filter expr(domain == ^arg(:domain))
    end

Which works as expected calling from Elixir, but when used in GraphQL:

  graphql do
    type :company

    queries do
      list :list_companies, :read, paginate_with: nil
      get :exists, :by_domain
      get :company_by_id, :by_id
      get :company_by_domain, :by_domain
    end

    mutations do
    end
  end

The generated schema wants there to be an argument of id: ID! in addition to the domain string argument.
