Describe the Bug

Astro seems not able to pre-render pages in a hybrid environment.
According to the manual, astro pages are always pre-rendered which should make it compatible with an hybrid installation.
However, using such config leads to no starlight page pre-rendered. All other astro pages, outside starlight, are prerendered. I found this noticing that during the build, pagefind was not finding any html page.

output: "hybrid",
  adapter: nodejs({
    mode: "standalone",
}),

Without the hybrid mode:

and with the hydrid mode enabled:

I am working to a reproducible example. The one on Stackblitz seems to work, but the exact same repo on my local macbook M3 does not.

Thanks for your report.

Is this the exact same repro you're testing or something similar? I'm asking because I just tried downloading the repro and building it on macOS and did not get the issue you're seeing.

The only change I made was removing the ../../assets/houston.webp mention in src/content/docs/index.mdx as I assume it's just an asset missing in StackBlitz.

I used the "Download ZIP" button in the file explorer to download the repro and ran npm install and npm run build as the configuration already contained output: "hybrid", and the Node.js adapter.

If you re-download the repro and try again, does it still fail for you?

[LunaticMuch]

It's the same one running from my local.
I built it because I have another repo which actually behave bizarrely in the same way. Only difference, I locally used a company proxy for downloading dependencies instead of the public npm registry.

I actually tried to reproduce it locally, using npmjs.org as registry, and I have it. This is way too weird.

Yes, I actually tried also from my own macbook...same issue. Do you know how could I potentially debug/trace it?

[LunaticMuch]

I think it's an astro related problem. I will open a bug there. Right now you can look the following logs for MacOS and Codesandbx

Same repo, different behaviour. The only real difference is the underlying OS.

Problem identified. Not a Starlight problem.
