🐛 BUG: Doing fetch requests in a Worker...

Hi, I have updated my workers and they are using 2.8.1 and now, when I do a env.SERVICE.fetch(request.clone()) it stalls with a " TypeError: Cannot construct a Request with a Request object that has already been used." And it was working before, both in local and deployed in CF. Could it be related to this issue https://github.com/cloudflare/wrangler2/issues/2589 ?

I'm using a "api-gateway"-like code:

const { pathname } = new URL(request.url);
    if (pathname.startsWith("/api/config")) {
      console.log(`Path ${pathname} requested. - Configuration`)
      return await env.configuration.fetch(request.clone());
    }

const { pathname } = new URL(request.url);
    if (pathname.startsWith("/api/config")) {
      console.log(`Path ${pathname} requested. - Configuration`)
      return await env.configuration.fetch(request.clone());
    }

And following what's explained here https://developers.cloudflare.com/workers/platform/bindings/about-service-bindings/#gateway-worker-and-service-bindings-usage

About Service bindings · Cloudflare Workers docs

Service bindings are an API that facilitate Worker-to-Worker communication via explicit bindings defined in your configuration.

The Cloudflare Blog

Service Bindings are generally available, with efficient pricing

Service bindings are an API that facilitate Worker-to-Worker communication. You can invoke other Workers directly from your code; making it possible to communicate with shared services. We’ll also make it cost-efficient to run multiple Workers

Oh, I will need to wait till there is a new version given https://github.com/cloudflare/wrangler2/pull/2597 was added after the 2.8.1 release cut.
