Currently, in the [icons_helper.rb](https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/helpers/icons_helper.rb#L178) we will throw an error on non-production environments if an icon is not found. ```ruby def known_sprites return if Rails.env.production? @known_sprites ||= Gitlab::Json.parse(File.read(Rails.root.join('node_modules/@gitlab/svgs/dist/icons.json')))['icons'] end def known_file_icon_sprites return if Rails.env.production? @known_file_icon_sprites ||= Gitlab::Json.parse(File.read(Rails.root.join('node_modules/@gitlab/svgs/dist/file_icons/file_icons.json')))['icons'] end ``` Ideally, we should avoid the production check and see if there's a more graceful way to fail regardless of the environment.
