Describe the bug

In Nuxt 3.8 a new feature was introduced which adds a new /_nuxt/builds/meta/<buildId>.json in the build output directory. This causes the following two new entries to be added to nitro.options.publicAssets:

{
  ...
  publicAssets: [
    ...
    {
      dir: '/Users/<me>/Projects/test/test-nuxt-3/.nuxt/manifest/meta',
      maxAge: 31536000,
      baseURL: '/_nuxt/builds/meta',
      fallthrough: false
    },
    {
      dir: '/Users/<me>/Projects/test/test-nuxt-3/.nuxt/manifest',
      maxAge: 1,
      baseURL: '/_nuxt/builds',
      fallthrough: false
    }
  ]
}

The Cloudflare Pages preset then "copies" these over when generating a _routes.json file:

{
  "version": 1,
  "include": [
    "/*"
  ],
  "exclude": [
    "/_nuxt/*",
    "/_nuxt/builds/*",
    "/_nuxt/builds/meta/*",
    ...
  ]
}

This results in the following error during deployment:

Error: Failed to publish your Function. Got error: Error 8000057: Overlapping rules in _routes.json are not allowed. Rule "/_nuxt/builds/*" is overlapped by "/_nuxt/*". Remove one of the rules to continue.

I originally created nuxt/nuxt#23796 when I discovered this issue, but according to the maintainer who responded it is Nitro's responsibility to ensure that the overlapping URLs created in nitro.options.publicAssets are correctly handled when creating _routes.json.

Additional context

For now this issue can be avoided with experimental: { appManifest: false } in nuxt.config.ts. However, this issue will come back again if any other overlapping URLs ever make it into nitro.options.publicAssets.

Logs

No response

When you use wrangler to create a nuxt application, you can also see this error.
That way you don't need to set up a build or a repo.

npm create cloudflare@latest my-nuxt-app -- --framework=nuxt

@atinux This was already mentioned in the posts' "Additional context", along with its downsides. Commenting the same again separately may lead to people incorrectly assuming it's a good long-term solution.

@favna read too fast sorry about this, deleted the comment to avoid any downsides.

The fix is released on nitro@2.7.2
