I have the following middleware. It works locally, but when my server is running with HTTPS, it for some reason tries to do the rewrite to https://localhost:8000, not http://localhost:8000. Why is that? I clearly specify the protocol as http://. My backend server and my front-end are running on the same VPC and node, so I just want to communicate over HTTP locally, but the middleware keeps injecting HTTPS. Is this a bug?

export function middleware(request: NextRequest) {
  const requestHeaders = new Headers(request.headers);

  const updatedUrl = request.nextUrl.clone();
  updatedUrl.host = "localhost:8000";
  updatedUrl.protocol = "http:";

  const response = NextResponse.rewrite(updatedUrl.toString(), {
    request: {
      headers: requestHeaders,
    },
  });
  return response;
}
