npm

Expected Behavior

I would expect all useLoaderData calls to return the loader data instead of null.

Actual Behavior

• Root has a loader
• Layout has a clientLoader + HydrateFallback
• Index has a loader

The layout clientLoader ensures the URL contains a search params p by throwing a redirection.

If you load the page without the URL search params (full page load), you'll see that root and index data become null but the layout route data in defined.
