How to configure the Visual Studio Code Debugger for Chrome

I'm unable to get the Visual Studio Code Debugger for Chrome running propertly in my environment. I was able to install and set a basic configuration

{ "version": "0.2.0", "configurations": [ { "type": "chrome", "request": "launch", "name": "Launch Chrome", "url": "localhost:7777/pls/lj_unittest/LAS_DLG_Startup.GO", "webRoot": "${workspaceFolder}", "trace": true, "sourceMaps": true } ] } 

for my project that now allows me to launch the Chrome browser from VSCode but I cannot really do anything else and when for example trying to set a break point in my sources the editor shows the Breakpoint set but not yet bound message on the break point and does not stop as expected.

I'm pretty sure that what I'm missing is to somehow link the TypeScript sources that I'm using with the actual resources that will be loaded by the browser but I cannot seem to understand on how to configure this.

My environment is as follows:

• The sources are in a src directory in the project root with a src directory that then split into modules, framework and global.
• I'm using webpack to build my resources with devtool set to eval-source-map.
• The start page (index.html) is generated dynamically on an Apache web server using the url localhost:7777/pls/lj_unittest/LAS_DLG_Startup.GO.
• The resources (JS, CSS, HTML, images, etc.) are accessed using the base url localhost:7777/q/p/lj_unittest/.
• The vscode-chrome-debug.txt file starts like this:
