Cloudflare Workers Serve Specific File from Function Issue

[path].ts

// This handler does a 301 redirect to `/test` in a loop until browser throws ERR_TOO_MANY_REDIRECTS (using wrangler@beta)
export const onRequest: PagesFunction<unknown> = async ({ request, env }) => {
  // The goal of this handler is to return a static file called `test.html`.
  
  // Parsing `/test.html` directly returns a URL parsing error as per issue https://github.com/cloudflare/wrangler2/issues/165
  const assetReq = new Request("http://fakehost/test.html", {
    cf: request.cf,
  });
  const response = await env.ASSETS.fetch(assetReq);
  return new Response(response.body, response);
};

// // As per issue https://github.com/cloudflare/wrangler2/issues/232 this acts as if `next();` was called and does not serve test.html
// export const onRequest: PagesFunction<unknown> = async ({ next }) => {
//   return next("http://fakehost/test.html");
// };
