I'm getting the same error in the playground after updating nitropack to 2.9.0 or higher, maybe related nuxt/nuxt#26170.

I haven't checked further (yet) if this is related to .yml files as you described.

I have added the a new reproduction (forked from the previous one) and change all .yml file into .json and it is working.

Now that unjs/nitro#2275 has been merged this issue can be resolved by overriding nitropack to install its nightly release (you will have to remove lockfiles before reinstalling). I have updated you reproduction to demonstrate here.

Not sure when then next nitro release will be, let's hope it's soon and that Nuxt includes it in the next release!

Let's keep this issue open until that's released, until then if anyone else runs into this add this to your package.json as a temporary workaround:

  "overrides": {
    "nitropack": "npm:nitropack-nightly"
  }

Thanks for the quick resolution 🔥
