Describe the issue

I follow this tutorial in official document next-auth, when i custom jwt method ( encode, decode )

NextAuthOptions: pages/api/auth/[...nextauth].ts

jwt: {
  maxAge: 60 * 60 * 24 * 14,
  async encode({ token: payload, secret }) {
    return jwt.sign(payload, secret);
  },
  async decode({ token, secret }) {
    return jwt.verify(token, secret) as any;
  },
}

and pass decode method above to middleware

middleware.ts

and i got error
