Astro assets can not be loaded with `rollupOptions.output.assetFileNames`

Hi, I'm migrating an Astro project from Cloudflare Pages to Cloudflare Workers using the @astrojs/cloudflare adapter. ( So it is SSR. ) After switching to Workers, I found that none of the assets are loading properly.

In my astro.config.mjs, I’ve set a custom asset file naming like this:

// astro.config.js
vite: {
  build: {
    rollupOptions: {
      output: {
        assetFileNames: 'assets/[ext]/[hash][extname]',
      },
    },
  },
},

// astro.config.js
vite: {
  build: {
    rollupOptions: {
      output: {
        assetFileNames: 'assets/[ext]/[hash][extname]',
      },
    },
  },
},

This configuration worked fine on Cloudflare Pages. But with Workers, all the built assets are being placed inside the _worker.js folder under .output/.

Here’s a minimal reproduction on StackBlitz.

But it isn't working on StackBlitz, so I deployed on Cloudflare Workers.

Is there anything I should configure differently to get assets to load properly with the Workers adapter?

Thanks in advance!
