VS Code debugging : breakpoint is not hitting

I have a sailsjs app in docker container and would like to debug through vs code. I currently have nodemon working and debugger listening at a port. Strangely my vs code is not hitting breakpoint.I tried below launch config.

"configurations": [
        {
            "name": "Docker: Attach To Node",
            "type": "node",
            "request": "attach",            
            "address": "localhost",
            "restart": true,
            "port": 9229,
            "localRoot": "${workspaceFolder}",
            "skipFiles": [
                "<node_internals>/**"
              ],
            "remoteRoot": "usr/src/app",
            "protocol": "inspector"
        },

On click on play green button nothing happens. VS code version 1.70.2. I am using windows 10.
