Describe the Bug

If I try to build the Astro 5 website with Starlight and Cloudflare adapter, the build error will occurs.

Build error log:

$ npm run build

00:47:37 [build] Building static entrypoints...

[commonjs--resolver] [plugin vite:resolve] Cannot bundle Node.js built-in "node:path" imported from "node_modules/@astrojs/starlight/utils/collection.ts". Consider disabling environments.ssr.noExternal or remove the built-in dependency.

What's the expected result?

No build errors.

No, but I found a workaround for this. I added this to the Astro config.

  vite: {
    ssr: {
      external: ["node:fs", "node:path", "node:url"],
    },
  },

I'm transfering to the Starlight repo, since AFAIK, this is caused by Starlight using node modules at runtime
