Better auth / Sveltekit user session doesn't work

+hooks.server.ts

const handleParaglide: Handle = i18n.handle();

const authHandle: Handle = async ({ event, resolve }) => {
    const session = await authClient.useSession();

    event.locals.session = session?.session;
    event.locals.user = session?.user;

    return svelteKitHandler({
        event,
        resolve,
        auth
    });
};

export const handle = sequence(authHandle, handleParaglide);
