How to make VSCode open original TS file of “src” when hitting a breakpoint in node app

Question

I have a CLI node app that I am trying to debug with VSCode. It works pretty well, however when hitting a breakpoint, VSCode opens a new code view from the source map file instead of the actual TS file located in my "src" folder. This is kind of annoying. When I run some JS code in a browser using VSCode as a debugger, VSCode opens the actual TS file as expected. How do I get this behavior also with node?

webpack.config.json :

const path = require("path");
const webpack = require("webpack");
const { merge } = require('webpack-merge');

const commonConfig = {

    entry: "./src/Startup.ts",
    module: {
        rules: [
            {

    }
}

const developmentConfig = {
    mode: 'development',
    devtool: 'source-map',
    stats: {
        warnings: false
    }
}

const productionConfig = {
    mode: 'production'
}

module.exports = (env, argv) => {
    switch(argv.mode) {
      case 'development':
        return merge(commonConfig, developmentConfig);
      case 'production':
        return merge(commonConfig, productionConfig);
      default:
        throw new Error(`Configuration '${argv.mode}' does not exists.`);
    }
}

The TS file paths generated by Webpack in the source map files are using the webpack protocol that VSCode did not understand. I solved it by adding this parameter in my webpack.config.js so the source map contains absolute paths to the TypeScript files instead:

const commonConfig = {
    output: {
        devtoolModuleFilenameTemplate: "[absolute-resource-path]",
    },
}
