[BUG] Route Handler request always return "n" instead of the worker's origin

[quanphung1120]

Describe the bug

export async function GET(
  request: NextRequest,
  { params }: { params: Promise<{ provider: string }> }
) {
  const url = new URL(request.nextUrl);
  const supabase = await createClient();
  const provider = (await params).provider as Provider;

  console.log("raw url: " + request.nextUrl);
  console.log("url: " + url);
  const { data, error } = await supabase.auth.signInWithOAuth({
    provider,
    options: {
      redirectTo: `${url.origin}/auth/callback`,
    },
  });

  console.log(`${url.origin}/auth/callback`);

  if (error || !data || !data.url) {
    return Response.json({ msg: "Failed to sign in" }, { status: 500 });
  }

  return redirect(data.url);
}

request.nextUrl always return "https://n/" instead of my worker custom domain.

Steps to reproduce

Create a route handler and call request.nextUrl

Expected behavior

It should return the correct url
