I add this
import type { NextConfig } from "next";

const nextConfig: NextConfig = {
serverExternalPackages: ["pdf-parse"],
};

export default nextConfig;

but it is not fixing this error

⨯ Error: Failed to load external module pdf-parse-08f4573089f02674: ReferenceError: DOMMatrix is not defined

I forgot to add this, now it is working fine
import "pdf-parse/worker";
