What steps will reproduce the bug?

1. Run these commands

npm init
npm install plawright
touch main.js
touch module.js

2. Add "type":"module" in package.json
3. Paste this code into module.js

import { test } from "playwright/test";

export const dummy = ''

4. Paste this code into main.js

import {mock} from "node:test";

// The module to mock could be anything
mock.module('node:fs')

const {dummy} = await import("./module.js");

5. Run node --experimental-test-module-mocks --experimental-require-module --experimental-detect-module module.js. Normally everything worked correctly

Note: the flags are needed to be able to use mock.module

6. Run node --experimental-test-module-mocks --experimental-require-module --experimental-detect-module main.js. Here you should see an error:

import { test } from "playwright/test";
         ^^^^
SyntaxError: The requested module 'playwright/test' does not provide an export named 'test'

What if I use const { test } = await import("playwright/test") instead

Now module.js is:

const { test } = await import("playwright/test");

export const dummy = ''

I get a new error:

node:internal/util:399
  validateFunction(original, 'original');
  ^

TypeError [ERR_INVALID_ARG_TYPE]: The "original" argument must be of type function. Received undefined

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

It is reproduced every single time, normally without a condition.

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

The expected behaviour is that the import occurs correctly and playwright is imported

What do you see instead?

An error (with import { test } from "playwright/test"):

import { test } from "playwright/test";
         ^^^^
SyntaxError: The requested module 'playwright/test' does not provide an export named 'test'

With const { test } = await import("playwright/test")

node:internal/util:399
  validateFunction(original, 'original');
  ^

Hi! Can this be reproduced without any dependencies (such as playwright)?

[AcePeaX]

I've tried with some node packages, it seems to work fine.

Note: It works fine with playwright, the problem is with playwright/test

[MoLow]

Please open an issue in the playwright repository, this is not an issue in node's core

[cjihrig]

Are we sure this isn't the issue @GeoffreyBooth is fixing in #53642?
