How to configure VSCode launch.json for debug?

'Breakpoint ignored because generated code not found (source map problem?).'

```
"configurations": [
{
"type": "chrome",
"request": "launch",
"name": "Launch Chrome against localhost",
"url": "http://localhost:3000",
"webRoot": "${workspaceRoot}",
"userDataDir": "${workspaceRoot}/.vscode/chrome",
"sourceMaps": true,
"skipFiles": [
"node_modules/**"
]
},
```

Start with the launch.json configuration shown in the issue and reproduce the debugger against http://localhost:3000. Check how the React app's generated code and source maps are being resolved; done means breakpoints bind instead of showing “generated code not found.”
