Session empty on Elysia server but works on Nextjs client

export const AuthMacro = new Elysia({ name: "auth" })
    .mount("/auth", auth.handler)
    .macro({
        auth: {
            async resolve({ status, request: { headers } }) {
                console.log(headers);
                const session = await auth.api.getSession({
                    headers,
                });
                console.log("server session", session);

                if (!session) return status(401);

                return {
                    user: session.user,
                    session: session.session,
                };
            },
        },
    });
