Node vs-code debugger is showing unbound breakpoint in Docker

Question

After much exploration I made the ts debugger work for specific port and also need to compile the .ts while doing live reload using nodemon. I was getting the same unbound breakpoint when I ran app without docker, but after changing the launch file it worked.

However in the docker the debugger is getting attached but with unbound breakpoint. What changes needs to be done for the launch file for debugger in "name": "my-service-docker",

For the docker, we need to set the right path for remoteRoot: which was /usr/src/app

 {
            "name": "my-service-docker",
            "type": "node",
            "request": "attach",
            "port": 9230,
            "restart": true,
            "sourceMaps": true,
            "address": "localhost",
            "localRoot": "${workspaceFolder}",
            "remoteRoot": "/usr/src/app",
            "protocol": "inspector"
        }
