Fog of war in React Router v7 is causing me problems with client-side useNavigate

[scottdickerson]

I'm using React Router as a...

library

Reproduction

I have a usecase where I have a main /account url. For non-mobile users (breakpoints measured client side) I need to redirect them to /account/details when that page initially renders and the client side code hydrates.

Inside the component:

return !isMobile ? <Navigate to="/account/details"/> : <AccountHome/>

Inside a client loader, same problem

    return !isMobile ? redirect('/account/details')

I get an error message in the console that says " Route /account/details does not exist"

If I manually reload the /account/details page it works.

If I do a 302 redirect from the server loader it works, but I can't determine the mobile or non-mobile from within that code.

This client-side navigate worked previously in Remix 2.x before my upgrade to React Router v7.

My assumption is that the Fog of War has caused the /account/details to be removed from the manifest until it detects that a user is about to visit that page.

I debugged into the react-router code and see that the route matches only contains my / and /account route while it's attempting to programmatically navigate to that /account/details so it fails navigation with that missing route error.

Used Package Manager

npm

Expected Behavior

I would expect the React-Rotuer client-side redirecting libraries to work with the manifest check even if the path I'm redirecting to had not yet been loaded by fog of war

Actual Behavior

I get this error with either a <Navigate or useNavigate from the initial render of this page.
