Error cause is not logged in dev:watch mode

Current behavior

I change tsconfig.json target to ES2022

I throw an error in onModuleInit in a service:

    onModuleInit() {
        try {
            this.method()
        } catch (error) {
            throw new Error('test 123', { cause: error })
        }
    }

    method() {
        throw new Error('cause 456')
    }

I run: nest start --watch

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

[1:27:41 PM] Starting compilation in watch mode...

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

While I was creating a reproduction repo, I realized that since you have ES2021 in your default tsconfig.json, that means you don't have to support ES2022. But still it would be nice to have error's cause to be logged.

[kamilmysliwiec]

Would you like to create a PR for this issue?

[micalevisk]

if you take a simple nodejs app like:

throw new Error('test 123', { cause: new Error('foo') })

then run node -r source-map-support/register app.js

you'll see the same behavior. So I don't think this is something to fix on Nestjs side

[micalevisk]

I guess we can close this in favor of evanw/node-source-map-support#337

But I don't think they would fix that soon
