Illegal access error when running a task from launch.json

[fetimo]

Issue Type: Bug

I have a launch.json file which runs this task:

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Jest Current File",
      "program": "${workspaceFolder}/node_modules/.bin/jest",
      "args": ["${relativeFile}"],
      "console": "integratedTerminal",
      "internalConsoleOptions": "neverOpen",
      "cwd": "${workspaceFolder}",
      "skipFiles": [
        "node_modules/**/*.js"
      ]
    }
  ]
}

It runs the task successfully but after it has run it produces the following error:

Debugger listening on ws://127.0.0.1:53058/320f84cc-741f-40da-a64b-736a4394e700

Downgrading to VS Code 1.46 fixes the issue.

This is a Node issue, captured in nodejs/node#27261

If the old debugger worked for you, you can try setting debug.javascript.usePreview: false to use it until the Node issue is fixed.
