How to redirect back to original page?

[vedantroy]

Inside, getServerSideProps, I have the following:

    return signedIn ? { props: ... } : { redirect: {
      destination: `/api/auth/signin?callback=${encodeURI(`${absoluteUrl(req, "localhost:3000").origin}${req.url}`)}`,
      permanent: false,
    }}

However, although this does successfully redirect the user to the login page if they are not signed in, it does not redirect the user back to the current page after a successful login. Am I using the callback query parameter incorrectly?

Oh wait, it's callbackUrl.
