When adding multiple set-cookie headers on response, it seems that cookies are overwritten or merged. This behaviour happends on Netlify and Cloudflare as far as i know with Nitro v2.4.1. Works fine on Vercel.

export default eventHandler((event) => {
  setCookie(event, "cookie_1", "cookie_1_value");
  setCookie(event, "cookie_2", "cookie_2_value");
  return { nitro: "Is Awesome!" };
});
