I tried the accepted answer and all the other variances and none worked for me, however what really works for me is to attach to the 9229 port. What I did is add/modify your launch.json with the following config

.vscode/launch.json

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "attach",
      "name": "Attach NestJS WS",
      "port": 9229,
      "restart": true,
      "stopOnEntry": false,
      "protocol": "inspector"
    }
  ]
}

and in package.json (Nest new CLI commands, requires 6.8.x, see this blog)

{
  "name": "nest-app",
  "scripts": {
    "start:debug": "nest start --debug --watch"
  }
}

and finally it works!
