graphql-yoga: Dependency cross-undici-fetch ponyfill has broken every fetch in my API

Describe the bug

I’ve recently moved to grpahql-yoga, and while it’s been absolutely fantastic, I’ve noticed a key part of my app is completely broken.

Before I was using isomorphic-unfetch to fetch an image url and then transforming it into a blob:

export const createFile = async (url: string): Promise<Blob> => {
  let response;
  try {
    response = await fetch(url);
  } catch (err: any) {
    throw new Error(err);
  }

  const blob = await response?.blob();

  return blob;
};

Since moving to graphql-yoga, any request done with any implementation of a server-side fetch fails:

error - uncaughtException: TypeError: Cannot read properties of undefined (reading 'get')
    at Function.value (/home/leonardo/commentcarp-api/node_modules/cross-undici-fetch/dist/create-node-ponyfill.js:198:26)

No matter what I install or what I import (tried with node-fetch, isomorphic-unfetch, cross-fetch), the error always mentions cross-undici-fetch/dist/create-node-ponyfill.js.

I think this ponyfill is overriding any fetch request I make, and since it fails my API is completely broken.
