Describe the Bug

Run npm run build and wait for the full build in the given https://stackblitz.com/edit/github-3k6n4e?file=astro.config.mjs to see the errors.

Errors:

07:34:56
 finalizing server assets

07:34:56 [build] Rearranging server assets...
07:34:56 [ERROR] [@astrojs/cloudflare] There was an error moving _headers to the root of the output directory.
07:34:56 [ERROR] [@astrojs/cloudflare] There was an error moving _redirects to the root of the output directory.
07:34:56 [ERROR] [@astrojs/cloudflare] There was an error moving _routes.json to the root of the output directory.
07:34:56 [build] Server built in 1.07s
07:34:56 [build] Complete!

According to this comment these files aren't even supported anyway?

What's the expected result?

No errors just like when working with astro dev or when I don't use a base path
