Can't attach debugger to Quasar main process

I'm building an electron application using Quasar Framework. I'm having some trouble debugging the main process of Electron of it with VS Code.

When I start my app with quasar dev -m electron I can see the debugger is listening:

Debugger listening on ws://127.0.0.1:5858/d2fa14ad-cc55-42e6-a81b-a7c71e6e5650

Then I created a launch.json config with the following:

{
    "type": "node",
    "request": "attach",
    "name": "Attach",
    "port": 5858
}

When I click to attach I can see the message Debugger attached but all my breakpoints set on files of the main process get greyed out with the message Breakpoint set but not yet bound:
