OpenVidu Angular project not hitting breakpoints


I am trying to debug the openvidu angular application and I cant seem to get it working in vscode. I have done the following: cloned the repo, npm install, ng serve and created a launch.json file: {
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: Debugging in Visual Studio Code
“version”: “0.2.0”,
“configurations”: [
“type”: “pwa-chrome”,
“request”: “launch”,
“name”: “Launch Chrome against localhost”,
“url”: “http://localhost:4200”,
“webRoot”: “${workspaceFolder}”

however when I put a breakpoint in on app.component.ts on the title = ‘OpenVidu Call’ it just never hits it and has a greyed out breakpoint. I have tried many suggestions online such as source maps : true, changing webroot to “webRoot”: “${workspaceFolder}/src/app” I have tried the suggestions here as well: vscode-recipes/Angular-CLI at master · microsoft/vscode-recipes · GitHub

Any ideas what I am doing wrong? I have tried a simple angular application and that works fine, however openvidu will not hit any breakpoints
