Integrating CKEditor into Sonata Admin: Fixing Resource Loading Issues

Question

I'm trying to integrate CKEditor into my Sonata admin panel. I installed it via composer require friendsofsymfony/ckeditor-bundle and updated the assets using php bin/console assets:install. When loading the page with a form field of type CKEditorType::class, the resource ckeditor.js loads fine (assets/bundles/fosckeditor/ckeditor-1cb7c0838d7fdf95d4aa4158bea9bdc0.js), but then it tries to load /bundles/fosckeditor/config.js?t=O7L9, /bundles/fosckeditor/skins/moono-lisa/editor.css?t=O7L9 and /bundles/fosckeditor/lang/ru.js?t=O7L9, which fail with a 404 error. Why aren't these three files loading the same way as ckeditor.js? The files exist in assets, and they are listed in public/assets/manifest.json. In the fos_ckeditor.yaml config, the default Twig template is specified as:

twig:
   form_themes:
      - '@FOSCKEditor/Form/ckeditor_widget.html.twig'
