TypeError("Received non-Uint8Array chunk") on readable web stream

[tai2]

Here's a minimal reproducible example https://github.com/tai2/zip.js-unzip-test

zip.js raises a runtime error when feeding Node's readable web streams.

Node.js v22.13.1

It looks like it's a bug in Node.js unfortunately. I can reproduce it with the code below which does not depend on zip.js.

import * as fs from "fs/promises";

const main = async () => {
  const filepath = "file.zip";
  const file = await fs.open(filepath);
  const readableStream = file.readableWebStream();
  const blob = await new Response(readableStream).blob();
};

await main();

It also looks like it's fixed in Node.js 24, see nodejs/node#54041. The same code runs fine in Node.js v24.12.0.
