Hello guys, I've just created the next.js app using pages router, but sometimes middleware and server-side function on each page when I used ssr is not working, even dynamic routing is empty, but if page is refreshed it's work as usual

package.json

"next": "^13.5.5",
"react": "18.2.0",
"react-dom": "18.2.0",

next.config.js

/** @type {import('next').NextConfig} */
const nextConfig = {
  reactStrictMode: true,
  swcMinify: true,
  output: 'standalone',
  ...otherConfig
};

im using Dockerfile like this example
https://github.com/vercel/next.js/blob/canary/examples/with-docker/Dockerfile

middleware.ts

export function middleware(request: NextRequest) {
  // parse user agent
  const {
    device: { type },
  } = userAgent(request);
  // check the viewport
  const viewport = userAgentViewportParser(type);
  // update the expected url
  request.nextUrl.pathname = `${viewport}${request.nextUrl.pathname}`;

  // return rewrited response
  return NextResponse.rewrite(request.nextUrl);
}
