Error: write EPIPE when using wrangler dev to run cloudflare worker using itty-router

I am trying to test run a cloudflare worker locally using wrangler dev (although I have the same issue when running npm start), and I keep getting an EPIPE error. The error message and code are below. I am on Ubunutu 22.04 if that is relevant. Is this a bug I should report (and, if so, to which project?), or am I doing something wrong?

Error

wrangler dev now uses local mode by default, powered by 🔥 Miniflare and 👷 workerd.
To run an edge preview session for your Worker, use wrangler dev --remote
Using vars defined in .dev.vars
Your worker has access to the following bindings:
- R2 Buckets:
  - R2_BUCKET: bucket

Node.js v20.1.0

Code

import { Router, RouterType, IRequest } from 'itty-router'

export interface Env {
    R2_BUCKET: R2Bucket;
}

const router: RouterType = Router();

const get_static = async (req: IRequest, env: Env): Promise<Response> => {
    const url = new URL(req.url);
    const key = url.pathname.slice(1);
    const object = await env.R2_BUCKET.get(key);
    if (object == null) {
        return new Response('404, not found!', { status: 404 });
    }
    const headers = new Headers();
    object.writeHttpMetadata(headers);
    headers.set('etag', object.etag);
    return new Response(object.body, { headers });
}

router.all('*', get_static);

export default {
    async fetch(request: Request, env: Env, ctx: ExecutionContext): Promise<Response> {
       return await router.handle(request, env, ctx);
    },
};

I do not get the error when running the hello world worker script, but once I import itty-router and try to run, the error occurs. I expected the worker to run a local server normally, but the error shown above results instead.
