Cannot clone Response with null body

[payellodevsupport]

We receive TypeError: Cannot read properties of undefined (reading 'stream') when trying to clone a response with null body.

let cloned = new Response(null, { status: 201 }).clone()

Hey! 👋 This looks like an error in undici, the package Miniflare uses to provide fetch, Response, FormData, etc. I'd suggest you open an issue there. 🙂

import { Response } from "undici";
new Response(null, { status: 201 }).clone();

Uncaught TypeError: Cannot read properties of undefined (reading 'stream')
