Firebase: broken pipe when using npm

Hi, I've been playing around with Deno and Firebase/Firestore, put together a short script: 
import "https://deno.land/x/xhr@0.4.3/mod.ts";
import { deleteApp, initializeApp } from "npm:firebase/app";
import { collection, getDocs, getFirestore } from "npm:firebase/firestore";

const firebaseConfig = JSON.parse(Deno.env.get("FIREBASE_CONFIG"));
const firebaseApp = initializeApp(firebaseConfig);
const db = getFirestore(firebaseApp);

(await getDocs(collection(db, "sample-collection"))).docs.forEach((doc) => {
  console.log(doc.data());
});

await deleteApp(firebaseApp);
import "https://deno.land/x/xhr@0.4.3/mod.ts";
import { deleteApp, initializeApp } from "npm:firebase/app";
import { collection, getDocs, getFirestore } from "npm:firebase/firestore";

const firebaseConfig = JSON.parse(Deno.env.get("FIREBASE_CONFIG"));
const firebaseApp = initializeApp(firebaseConfig);
const db = getFirestore(firebaseApp);

(await getDocs(collection(db, "sample-collection"))).docs.forEach((doc) => {
  console.log(doc.data());
});

await deleteApp(firebaseApp);
which, if I run (locally or in docker container, deno version 2.2.5), I get the following: 
export FIREBASE_CONFIG='<CONFIG>' && deno run --node-modules-dir --allow-scripts=npm:@firebase/util@1.11.0,npm:protobufjs@7.4.0 --allow-env --allow-net test.js
{ "sample-field": "sample-value" }
error: Uncaught (in promise) Error: stream closed because of a broken pipe
    at async node:http2:824:44
export FIREBASE_CONFIG='<CONFIG>' && deno run --node-modules-dir --allow-scripts=npm:@firebase/util@1.11.0,npm:protobufjs@7.4.0 --allow-env --allow-net test.js
{ "sample-field": "sample-value" }
error: Uncaught (in promise) Error: stream closed because of a broken pipe
    at async node:http2:824:44
now if I change the imports to esm.sh ones, the issue with broken pipe goes away: 
import "https://deno.land/x/xhr@0.4.3/mod.ts";
import { deleteApp, initializeApp } from "https://esm.sh/firebase@11.5.0/app";
import { collection, getDocs, getFirestore } from "https://esm.sh/firebase@11.5.0/firestore";

const firebaseConfig = JSON.parse(Deno.env.get("FIREBASE_CONFIG"));
const firebaseApp = initializeApp(firebaseConfig);
const db = getFirestore(firebaseApp);

(await getDocs(collection(db, "sample-collection"))).docs.forEach((doc) => {
  console.log(doc.data());
});

await deleteApp(firebaseApp);
import "https://deno.land/x/xhr@0.4.3/mod.ts";
import { deleteApp, initializeApp } from "https://esm.sh/firebase@11.5.0/app";
import { collection, getDocs, getFirestore } from "https://esm.sh/firebase@11.5.0/firestore";

const firebaseConfig = JSON.parse(Deno.env.get("FIREBASE_CONFIG"));
const firebaseApp = initializeApp(firebaseConfig);
const db = getFirestore(firebaseApp);

(await getDocs(collection(db, "sample-collection"))).docs.forEach((doc) => {
  console.log(doc.data());
});

await deleteApp(firebaseApp);
when ran, the output is 
export FIREBASE_CONFIG='<CONFIG>' && deno run --allow-env --allow-net test.js
{ "sample-field": "sample-value" }
export FIREBASE_CONFIG='<CONFIG>' && deno run --allow-env --allow-net test.js
{ "sample-field": "sample-value" }
(no broken pipe, the exit status is 0) --- Could someone help me understand the difference between these approaches? Afaik the imported packages versions are matching, is there some other difference?

That sounds like an unexpected behaviour. Can you file an issue for that here https://github.com/denoland/deno/issues ? My guess is that we have. a bug in our node streams implementation. esm.sh transpile stuff and likely gives you the browser entry of the firebase package vs the node one. And their browser entry likely uses web streams instead of node streams

I was thinking an issue might be a better thing to do, but wanted to confirm first that I'm not doing anything wrong, thanks for the suggestion, I'll file it shortly.
