Can't load assets ressources (css + js) in production with Rails 6

Question

When I start my application in production mode the assets (css + js) don't load correctly.

I get in browser's console net::ERR_ABORTED 404 (Not Found) or in Rails log ActionController::RoutingError (No route matches [GET] "/packs/js/application-51bdb73d26ac893c3407.js"):

I made rake assets:precompile and also turned config.assets.compile = true in environments/production.rb but same result

For the production mode I used the same app and the same directory I just add -e production as argument to the rails server command

Seems like you should set RAILS_SERVE_STATIC_FILES environment variable to true

Suggestion is based on this issue comment I found while resolving same trouble

This only affects configuration at config/environments/production.rb:

  # Disable serving static files from the `/public` folder by default since
  # Apache or NGINX already handles this.
  config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?
