ActionView :: Template :: Error Webpacker не может найти пакет приложений

Question

Мои настройки приложения - Rails 5.2.2 + Capistrano + Webpacker.

Я обновил webpacker с версии 4.0.0-pre.2 до 4.0.0-rc3, заменил javascript_pack_tag до javascript_packs_with_chunks_tag в соответствии с официальной рекомендацией.

Когда я пытаюсь загрузить страницу приложения в производство (разработка в порядке), я получаю следующую ошибку:

ActionView::Template::Error (Webpacker can't find application-bundle in /var/www/my_app/releases/20190118230511/public/packs/manifest.json. Possible causes:
1. You want to set webpacker.yml value of compile to true for your environment
   unless you are using the `webpack -w` or the webpack-dev-server.
2. webpack has not yet re-run to reflect updates.
3. You have misconfigured Webpacker's config/webpacker.yml file.
4. Your webpack configuration is not creating a manifest.
Your manifest contains:
{
  "application-bundle.js": "/packs/application-bundle-d19ff417e51c4d079a26.chunk.js",
  "application-bundle.js.map": "/packs/application-bundle-d19ff417e51c4d079a26.chunk.js.map",

Манифест также представляется правильным:

Кстати, environment.splitChunks(); здесь правильно?

Есть идеи, что может быть не так?
