npm:undici fetch() fails to resolve with large buffer

[AFKBETO]

Hi, I have encountered a problem with undici on Deno.

When use undici's fetch() method to fetch a file sufficiently large, the promise fails to resolve. This is not the case on node.js. You can reproduce this issue through the following codes:

import { Buffer } from "node:buffer";
import { fetch } from 'undici';

const url = ''; // url for a remote file/image

if (import.meta.main) {

	const result = await fetch(url);
	const arr = await result.arrayBuffer();

	console.log(arr);

	const buffer = Buffer.from(arr);
	console.log(buffer);
}

With an image of ~40kB, this code fails to run on deno:

Tested ok with a 2-3kB image:

Version:

• Deno 2.2.5
• v8 13.5.212.4-rusty
• typescript 5.7.3
• Windows 11

Test image:
Big image (~40kB) and fail:

Small image (~2kB) and success:

finished(internalResponse.body.stream, () => {

is silently throwing the error

TypeError [ERR_INVALID_ARG_TYPE]: The "stream" argument must be an instance of Stream. Received an instance of ReadableStream

    at fetchFinale (file:///.../node_modules/undici/lib/web/fetch/index.js:1094:9)
    ...

Avoiding this error seems to fix the issue.

Node checks in eos if the passed stream is a web stream or a Node stream: https://github.com/nodejs/node/blob/ffc1cf620550180b2192cba9a4785a06075e5b6f/lib/internal/streams/end-of-stream.js#L68
