Aggregate errors or errors with cause are not logged

[steverep]

Bug report

What is the current behavior?

If an AggregateError or Error with cause is thrown, Webpack intercepts and only logs the primary message. For these cases, that message is often just an annotation on the real error, making it impossible to debug them from a Webpack plugin.

If the current behavior is a bug, please provide the steps to reproduce.

Throw an instance of AggregateError or an instance of Error with a cause property from any plugin, and then just examine the console output.

What is the expected behavior?

• For AggregateError, each of the errors should be logged
• For Error with cause, the cause should be logged as well

webpack version: 5.89.0

I seem to have the same problem.

I tried the following in NestJS with nest start --watch:

    try {
      await this.createEventStream()
    } catch (error) {
      throw new Error('creating stream', { cause: error })
    }

In the terminal I see that the cause is not logged:

.../src/subscriber/subscriber.service.ts:44
      throw new Error('creating stream', { cause: error })
            ^
Error: creating stream
    at SubscriberService.onModuleInit (.../src/subscriber/subscriber.service.ts:44:13)

    at NestApplication.listen (.../node_modules/@nestjs/core/nest-application.js:169:33)
    at bootstrap (.../src/main.ts:18:3)

When I run nest build and then node dist/main, I have the expected stack trace:

.../dist/subscriber/subscriber.service.js:37
            throw new Error('creating stream', { cause: error });
                  ^

}

The webpack version that is used by nest cli is 5.90.1.

In my case it seems it's not webpack, my error is logged somewhere else in Nest.
