With Next.js13 app-directory, Fetch API cause error when optional argument set

[ebifran]

Here is my app/page.tsx code.(experimental-edge is enabled)

export default async function Page() {
  // OK
  const json = await fetch("https://jsonplaceholder.typicode.com/todos/1").then(
    (res) => res.json()
  );

  // Error
  const json = await fetch("https://jsonplaceholder.typicode.com/todos/1", {
    method: "GET",
  }).then((res) => res.json());

  return (
    <>
      <p>{json.userId}</p>
      <p>{json.title}</p>
    </>
  );
}

How do I process fetch api above without error? Node.js version of my Cloudflare pages settings is 16.14.

I submited issue on github @cloudflare/next-on-pages, but I could not judge this error is caused by next.js edge-runtime or Cloudflare-pages.

Thanks.
