trpc v11 error: The transformer property has moved to httpLink/httpBatchLink/wsLink

Just upgraded tRPC to v11 and I directly got this error: Type typeof SuperJSON is not assignable to type TypeError<"The transformer property has moved to httpLink/httpBatchLink/wsLink"> Type typeof SuperJSON is not assignable to type "The transformer property has moved to httpLink/httpBatchLink/wsLink" My client initialization of tRPC:

  if (typeof window !== "undefined") return ""; // browser should use relative url
  if (process.env.VERCEL_URL) return `https://${process.env.VERCEL_URL}`; // SSR should use vercel url
  return `http://localhost:${process.env.PORT ?? 3000}`; // dev SSR should use localhost
