Unable to use relative URL with Svelte

import { authClient } from "$lib/client";

export const load: LayoutServerLoad = async ({ fetch }) => {
  const { data: session } = await authClient.getSession();

  const { data: hasAdminPerms } = await authClient.admin.hasPermission({
    userId: session?.user.id,
    permission: {
      adminDashboard: ["read"],
    },
  });

  return {
    hasAdminPerms,
  };
};

Error: Cannot use relative URL (/api/auth/get-session) with global fetch — use `event.fetch` instead: https://svelte.dev/docs/kit/web-standards#fetch-apis
