Top-level await is currently not supported with the iife output format. [ESBUILD]

[andreimerfu]

The example isn't working for me when I'm trying to implement it into a Rails 7.1 project with ESBUILD and Tailwind.

$ esbuild app/javascript/*.* --bundle --sourcemap --outdir=app/assets/builds --public-path=/assets
X [ERROR] Top-level await is currently not supported with the "iife" output format

    app/javascript/application.js:84:0:
      84 │ await window.LambdaCable.start();
         ╵ ~~~~~

Edit: I've manage to solve this by using something like this:

(async () => {
  await window.LambdaCable.start()
})();

However it's still not working.. The browser tries to make requests to the CloudFront distribution instead of the API Gateway. The action_cable.mount_path and action_cable.url are overwritten in the production.rb. Any ideas?
