Is this correct way to do session error handling in tanstack router (React)

export const Route = createFileRoute("/_authenticated")({
  loader: async () => {
    const isAuthenticated =
      window.localStorage.getItem("isAuthenticated") === "true";

    if (!isAuthenticated) {
      await signOut({
        fetchOptions: {
          onSuccess: () => {
            throw redirect({
              to: "/get-started", // redirect to login page
            });
          },
        },
      });
    }

    const { data: sessionData, error } = await authClient.getSession();

    if ((!sessionData && !error) || !isAuthenticated) {
      window.localStorage.removeItem("isAuthenticated");

      throw redirect({
        to: "/get-started", // redirect to login page
      });
    }

    return { sessionData, error };
  },
  staleTime: 10_000,
  component: () => <AuthComponent />,
});
