Rewrites has a bug and cannot download files?

[bbhxwl]

Summary

I have an API that enables backend conversion of different file formats, but errors occur when using NextJS.

import type { NextConfig } from "next";

const nextConfig: NextConfig = {
    output: "standalone",
    async rewrites() {
        return [
            {
                source: '/api/v1/:path*',
                destination: (process.env.NEXT_API_BASE as string) ?? "http://localhost:5012/Api/v1/Web/:path*",
            },
        ]
    },
};

export default nextConfig;

Failed to proxy http://localhost:5009/Api/v1/Web/FileFormatApi_Convert [Error: socket hang up] { code: 'ECONNRESET' }
