Rails Font CORS policy

I can't load this font for a CORS Policy.

Folder: app/assets/fonts/Inter-UI.var.woff2

<%=preload_link_tag("Inter-UI.var.woff2", as:'font', crossorigin: "anonymous")%>

Error:

Access to font at 'http://localhost:3000/assets/Inter-UI.var-e2e323d19d24946c4d481135af27ba00f3266aa9d4abe4262e97088feccb6ca4.woff2' from origin 'http://0.0.0.0:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Response HTTP status code

enter image description here

If I go directly to http://localhost:3000/assets/Inter-UI.var-e2e323d19d24946c4d481135af27ba00f3266aa9d4abe4262e97088feccb6ca4.woff2 I can download the file successfully.

I have already tried with rack-cors gem, but it's not working

config/environments/development.rb

Rails.application.configure do

  config.middleware.insert_before 0, Rack::Cors do
    allow do
      origins '*'
      resource '*', :headers => :any, :methods => :any
    end
  end

application.rb

 config.assets.precompile << /\.(?:svg|eot|woff|ttf|woff2)$/

assets.rb

Rails.application.config.assets.paths << Rails.root.join("app", "assets", "fonts")

CSS

    @font-face {
  font-family: 'Inter UI';
  font-style: italic;
  font-weight: 400;
  font-display: swap;
  unicode-range: U+000-5FF;
  src: font-url("/assets/fonts/Inter-UI.var.woff2") format("woff2-variations"), font-url("/assets/fonts/Inter-UI-Italic.woff2") format("woff2"), font-url("/assets/fonts/Inter-UI-Italic.woff") format("woff"); }

Try adding this to application.rb

Rails.application.config.assets.precompile << /\.(?:svg|eot|woff|ttf|woff2)$/

and update

Rails.application.configure do

  config.middleware.insert_before 0, Rack::Cors do
    allow do
      origins '*'
      resource '*', :headers => :any, :methods => :any
    end
  end
end

with

Rails.application.configure do

  config.middleware.insert_before 0, Rack::Cors do
    allow do
      origins '*'
      resource '*', :headers => :any, :methods => :any
    end
  end

  allow do
    origins "*"
    resource "/assets/*", methods: :get,  headers: :any
   end
end

and you can simply use

<%= preload_link_tag("Inter-UI.var.woff2") %>



@font-face {
  font-family: 'Inter UI';
  font-style: italic;
  font-weight: 400;
  font-display: swap;
  unicode-range: U+000-5FF;
  src: font_url("Inter-UI.var.woff2") format("woff2-variations"), 
       font_url("Inter-UI-Italic.woff2") format("woff2"), 
       font_url("Inter-UI-Italic.woff") format("woff"); 
 }

and if you are using fonts.css.erb inside the stylesheets do

@font-face {
      font-family: 'Inter UI';
      font-style: italic;
      font-weight: 400;
      font-display: swap;
      unicode-range: U+000-5FF;
      src: url(<%= asset_path "Inter-UI.var.woff2" %>) format("woff2-variations"), 
           url(<%= asset_path "Inter-UI-Italic.woff2" %>) format("woff2"), 
           url(<%= asset_path "Inter-UI-Italic.woff" %>) format("woff"); 
     }

and do rake assets:precompile
