visual studio code chrome debugger not working

Hi, I have opened node js(angular application) in visual studio code V 1.60.0. and I have installed chrome debugger extension.

 launch.json file to looks something like this

{
"version": "0.2.0",
"configurations": [
{
"type": "chrome",
"request": "launch",
"name": "launch to Chrome",
"port": 4200,
"urlFilter": "http://localhost:4200/*",
"webRoot": "${workspaceFolder}"
}
]
}

I enabled the break point and run the vsc.But the break point is always unbound. How to solve this issue.
