Here I have this simple snippet to get User's email from Session in a Server component:

export async function Email () {
  const session = await getServerSession(authOptions);
  
  if (session?.user) {
    // @ts-expect-error
    return session?.user.user.email
  }

  return (
    <p>email null</p>
  )
}

My question is why my session.user.email is empty and I can only get the email from session.user.user.email?
