Is that normal that auth() return serialized data ?

I'm using session callback in auth.ts with prisma ORM

  async session({ session, token }) {
      session.user = await prisma.user.findUniqueOrThrow({ where: { id: token.sub } });

      return session;
    },

As prisma returns Date instance for DateTime type, they get passed to session.user

If you display session.user.createdAt inside the session callback, you get an object.

elsewhere auth() returns a string. (because of serialization).

Is that an expected behavior ? Even of server component ?
Therefore my typing get wrong. And i can have very strange issues, where you are supposing having a date object and you have a string that cause bad behavior silently.

Thanks

I have been forced to do this using superjson and now this works.

A wrapper around auth

// Session Cb
 async session({ session, token }) {
      session.user.content = superjson.stringify(
        await prisma.user.findUniqueOrThrow({ where: { id: token.sub } }),
      );

      return session;
    },
  },

// Wrapper
const auth = cache(async () => {
  const session = await defaultAuth();

  return session
    ? {
        expires: session.expires,
        user: superjson.parse<SessionUser>(session.user.content),
      }
    : null;
});

Note

Therefore I'm still not sure if it's the correct place to fetch user. Doc doesn't shows anything.
