          def show
            raise ActiveRecord::RecordNotFound if spree_current_user.nil?

            render_serialized_payload { serialize_resource(resource) }
          end

          private

          def resource
            spree_current_user
          end

          def serialize_resource(resource)
            dependencies[:resource_serializer].new(
