What steps will reproduce the bug?

While making a request and accessing AsyncLocalStorage, inside asyncLocalStorage the finished module is executed to access the value stored in the local storage.

const asyncHooks = require('async_hooks')
const http = require('http')
const finished = require('stream').finished
const assert = require('assert')

const asyncLocalStorage = new asyncHooks.AsyncLocalStorage()
const store = { foo: 'bar' }

var server = http.createServer(function (req, res) {
  asyncLocalStorage.run(store, function () {
    finished(res, function () {
      assert.strictEqual(asyncLocalStorage.getStore()?.foo, 'bar')
    })
  })
  setTimeout(res.end.bind(res), 0)

}).listen(0, function () {
  var port = this.address().port
  http.get('http://127.0.0.1:' + port, function onResponse(res) {
    res.resume()
    res.on('end', server.close.bind(server))
  })
})

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

It should be able to access the value stored in the local storage.

What do you see instead?

undefined

Additional information

This is a test inside on-finished (see https://github.com/jshttp/on-finished/blob/f8b5f4097d28df79e466d1ffdf58ccb27d769156/test/test.js#L74)

This is important in order to use the finished function within the body-parser package. It's part of my experiment to stop using on-finished, but it will likely be merged if it passes all the tests, since the idea is to use the APIs provided by Node.js
