Strange error when testing with Auth.js v5

import { createInnerTRPCContext } from "./../server/api/trpc";

test("hello test", async () => {
  const ctx = createInnerTRPCContext({
    session: {
      user: { id: "123", name: "John Doe" },
      expires: "1",
    },
  });
  const caller = createCaller(ctx);

  const res = await caller.test.hello();
});

import { auth } from "@/app/api/auth/[...nextauth]/auth";

export const createTRPCContext = async (opts: { headers: Headers }) => {
  const session = await auth();

  return createInnerTRPCContext({ session });
};
