interceptors.responseError does not raise networking errors

interceptors.responseError does not raise networking errors

When the interceptors.responseError interceptor is used, this does not raise network errors, returning the request as if it had been successful.

Reproducible By

import { Pool } from "undici";

const URL = "https://foo.bar.ciao.com"; // <- URL does not exist

async function main() {
  const client = new Pool(URL);

  try {
    const response = await client
      .compose(interceptors.responseError({ throwOnError: true }))
      .request({ method: "GET", path: "/" });

    console.log(response.statusCode);
  } catch (e) { // <- not raised
    console.log(e);
  }
}

if (require.main === module) {
  void main();
}

Expected Behavior

request raises an error Error: getaddrinfo ENOTFOUND. This is raised when we don't use interceptors.responseError

Environment

• node: 20.18
• undici: 7.1.0

I think the problem is here. The error is the second parameter (not included)
