Hey guys I am using lucia for authentication and I want to add protected routes. So I made an api route to verify the cookie. But the problem is that I can't access the cookie in my api route.

'use server';

import { verifyAuth } from "@/lib/db";
import { cookies } from "next/headers";

export async function GET(request) {
    const result = await verifyAuth();
    const cookie = cookies().get('auth_session');
    console.log(cookie);
    console.log(result);
    return new Response(JSON.stringify({ user: result.user }), {
        headers: { 'Content-Type': 'application/json' },
    });

}

The result is {user:null,session:null} and the cookie is undefined.

export async function verifyAuth() {
    const sessionCookie = cookies().get(lucia.sessionCookieName);
    if (!sessionCookie) {
        return {
            user: null,
            session: null
        };
    }

    const sessionId = sessionCookie.value;

    if (!sessionId) {
        return {
            user: null,
            session: null
        };
    }

    const result = await lucia.validateSession(sessionId);

    try {
        if (result.session && result.session.fresh) {
            const sessionCookie = lucia.createSessionCookie(result.session.id); //refresh session
            cookies().set(sessionCookie.name, sessionCookie.value, sessionCookie.attributes);
        }
        else {
            const sessionCookie = lucia.createBlankSessionCookie(); // clear expired cookie
            cookies().set(sessionCookie.name, sessionCookie.value, sessionCookie.attributes);
        }
    }
    catch (e) {
        console.log(e);
    }
    return result;
}

I don't understand why this is happening. What should i do?
