Describe the Bug

Observed behavior

I'm using https://www.npmjs.com/package/fast-xml-parser to parse some XML documents from URLs, and it's not possible to test some locally because wrangler crashes.

Expected behavior

Wrangler shouldn't crash?

Steps to reproduce

import { XMLParser } from "fast-xml-parser";

const res = await fetch("https://kubernetes.io/feed.xml");

const { feed } = new XMLParser().parse(await res.text());

Please provide a link to a minimal reproduction

This is most probably because in wrangler dev we send the response body in a message over to the "inspector" (i.e. for attaching a debugger) via a WebSocket, and that has a limit on message size. We have a PR on workerd that could allow us to set this to a larger value - see cloudflare/workerd#2164.

This should be fixed now (cloudflare/workerd#2164 was merged and released)
