Pleroma.Web.AdminAPI.ConfigController: dialyzer error

lib/pleroma/web/admin_api/controllers/config_controller.ex:162:call
The function call will not succeed.

Phoenix.Controller.render(
  _conn :: %{:body_params => %{:configs => _, _ => _}, _ => _},

  %{:configs => [any()], :need_reboot => _}

will never return since the success typing is:
