SSR routes return 404 when layout present only in parent

[gavry]

I receive this error from the prod server:

app serve: Server running on http://0.0.0.0:8080

I'm using:

• Bun (1.1.43)
• Node (v20.18.1)
• one (1.1.411)
• SSR as the default render mode

My file structure is like this:

app/
    _layout.tsx
    home/
        _layout.tsx
        index+ssg.tsx
        search/
            _layout.tsx
            [query].tsx

The app-level _layout I've left there the whole time. For the other 2, I think it works fine when any of:

• both _layout files are present
• both _layout files are gone
• the layout is only present in search

But it breaks when:

• the layout is only present in /home, but not in /search.

I'm reasonably sure that this occurs with SPA-mode as well, but can double check! I would guess there's a central cause, but obviously I don't know.

I also have run into the same logged issue with a bunch of different combinations of file structures, including using (core) or [query] as folders. They've all worked completely fine in development, but then certain routes would break. And, most of the routes still work in prod. This is just the first time I nailed it down to one finite change that broke it! Happy to try to help, but I'm not exactly sure where it's best to start!

This issue may have been fixed in a more recent version. The current code at oneServe.ts:191 uses optional chaining (buildInfo?.cleanPath) which should handle the undefined case gracefully.

Could you try upgrading to the latest version of One and see if the issue persists? If it does, please share:

1. Your current One version
2. Your full file structure (with all _layout.tsx files)
3. The render mode of each route (SSR, SSG, SPA)

This will help us reproduce and fix any remaining issues.
