`append()` fails after upgrading from v6 to v7

[soulchild]

Since upgrading from archiver@6 to archiver@7, my application fails with the following error:

ArchiverError: input source must be valid Stream or Buffer instance

I'm basically creating a zip of zips. Here's a minimal reproduction of the issue:

import archiver from 'archiver';
import { randomUUID } from 'node:crypto';

const createZip = (files) => {
  const archive = archiver('zip');
  for (const file of files) {
    archive.append(file, { name: randomUUID() });
  }
  archive.finalize();
  return archive;
};

const zip = createZip(['foobar']);
createZip([zip]);

I don't see anything listed in the CHANGELOG about there being a breaking change, so maybe one of the upgraded transient dependencies is the culprit?

Thanks for any hints!

the major change was node 12 support dropped across archiver repos which did include version bumps of dependencies like readable-stream.

I know we have tests for appending streams but not sure I've tried to pass archiver stream in this way.

[ctalkington]

it does look like archiver-utils has stream detection issues with newer readable-stream v4 as shown with a failing test here:

https://github.com/archiverjs/archiver-utils/pull/149

should be resolved (additional test added across repos) in next point release

Awesome, @ctalkington! Thanks for the quick fix. I'll let you know if there's still a problem after upgrading to the next release.
