Hope everyone is doing well

I have a problem related to nextjs proxy and also related to nodejs.
When user send req to /api using frontend domain it must redirect him to backend domain and this working well but only in developement mode once i do npm run build, it gives me multiple errors saying can't fetch which basically mean that redirection logic doesn't work on production mode

module.exports = { async rewrites() { return [ { source: "/api/:path*", destination: "https://backend.vercel.app/:path*", // Proxy to Backend }, ]; }, }

I will leave this message in here in case someone had this problem before. Thank you
