Keep an eye on Render Notices

LogicException: Render context is empty, because render() was called outside of a renderRoot() or renderPlain() call. Use renderPlain()/renderRoot() or #lazy_builder/#pre_render instead. in Drupal\Core\Render\Renderer->doRender() (line 260 of /code/web/core/lib/Drupal/Core/Render/Renderer.php).

unsure currently of source. first thought was auctions_node_view(). but maybe in auction_mail. error was appearing after bid submit
during general feature testing.
-Drupal Core 10.1.6, basic Standard profile.
