Cannot find fs/promises in Bruno scripting

[luccitan]

I have checked the following:

• I use the newest version of bruno.
• I've searched existing issues and found nothing related to my issue.

Describe the bug

I am trying to write a pre-request script for my whole collection, and that script relies on puppeteer.

With this import :

try {
  const puppeteer = require('puppeteer');
} catch (error) {
  console.log(error.stack);
  throw error;
}

I get this as a response :

Error invoking remote method 'send-http-request': VMError: Cannot find module 'fs/promises'

I tried with multiple versions of puppeteer, but this does not seem relevant as fs/promises should be available for Node > 14, and current Bruno uses Node 16.16 if I'm not mistaken

.bru file to reproduce the bug

No response

Error logged from catching described above :

Dump from console.log(process.versions) in my Bruno script :

My Bruno package.json :

{
    "name": "<MY_PROJECT>",
    "version": "1.0.0",
    "main": "index.js",
    "dependencies": {
        "puppeteer": "^22.11.2"
    }
}

Have you tried enable puppeteer in bruno.json by whitelisting it ?

Have you tried enable puppeteer in bruno.json by whitelisting it ?

I managed to go beyond this error by whitelisting bultin modules that failed to be loaded :

  "scripts": {
    "moduleWhitelist": [
      "fs/promises",
      "os",
      "child_process",
      "readline",
      "net",
      "tty",
      "tls",
      "crypto",
      "events"
    ],
    "filesystemAccess": {
      "allow": true
    }
  }

but now I have issues because process.stderr seems to be undefined under Electron

I'm not sure you can access fs in the scripts, as those are exectued on client side (nextJs), not on the backend (Electron)
