Describe the Bug

When deploying to Cloudflare Workers using a base-path, I am presented with:

⛅️ wrangler 4.54.0
───────────────────
▲ [WARNING] Warning: The following routes will attempt to serve Assets on a configured path:

    • my-app.com/garden* (Will match assets: dist/garden*)

  Requests not matching an asset will be forwarded to the Worker's code.


🌀 Building list of assets...
✨ Read 52 files from the assets directory /Users/jilles/Code/small-app-garden/small-app-garden-astro/dist

✘ [ERROR] Uploading a Pages _worker.js directory as an asset.

  This could expose your private server-side code to the public Internet. Is this intended?
  If you do not want to upload this directory, either remove it or add an ".assetsignore" file, to
  the root of your asset directory, containing "_worker.js" to avoid uploading.
  If you do want to upload this directory, you can add an empty ".assetsignore" file, to the root of
  your asset directory, to hide this error.


🪵  Logs were written to "/Users/jilles/.config/.wrangler/logs/wrangler-2026-01-07_02-27-32_113.log"

However, it works fine without a path! I got a workaround by adding a copy step to the build script:

		"build": "astro build && cp public/.assetsignore dist/.assetsignore",

Steps to repreduce:

$ pnpm create cloudflare@latest astro-bug-example
(choose minimal)
(git)
(deploy yes)

Deploys to
https://astro-bug-example.[your acccount].workers.dev

Open up Astro config and set base/path

  site: 'https://astro-bug-example.[your account].workers.dev',
  base: 'example',

Run deploy:

What's the expected result?

It deploys without error.
