Request URL is always http://... even when the request is made with HTTPS. Is this intended? Is there a workaround?

[syhner]

When implementing a simple server

const server = Bun.serve({
  fetch: (request) => new Response(request.url),
  tls: {
    cert: Bun.file('cert.pem'),
    key: Bun.file('key.pem'),
  },
});

the request.url will only be https://... if a valid tls object is provided to Bun.serve.

However there are not always PEM files which can be provided (i.e. using a 3rd party service to handle TLS, or using a runtime which does not support the file system).

Is this intended behaviour, and is there a workaround?
