How to debug Node TypeScript in Visual Studio Code when the JavaScript source is in a different folder

From Visual Studio Code, I am able to debug and step through the TypeScript source of Main.ts, provided the JavaScript and map files coexist in the same folder as the TypeScript source.

This arrangement works -

debugDemo\
     .vscode
              launch.json        
     TypeScript\
               Main.ts
               Main.js
               Main.js.map

However, I don't want the JavaScript files in the TypeScript folder, but instead would like the JavaScript in the JavaScript folder. I understand this can be achieved via a launch.json configuration using the outFiles attribute to identify where to locate the JavaScript.

For me, this arrangement does not work -

debugDemo\
     .vscode
              launch.json        
     TypeScript\
               Main.ts
    JavaScript\        
               Main.js
               Main.js.map

The error is always - "Cannot launch program 'c:\debugDemo\TypeScript\Main.ts'; setting the 'outFiles' attribute might help"

What is wrong, how can I configure Visual Studio Code to look for the JavaScript files in the JavaScript folder? I experimented with various glob patterns for outFiles, but it did not help resolve the issue.

Main.ts Reduced to one line of code to reduce the problem complexity

  console.log("debug"); 

Mapfiles built via

tsc --sourcemap TypeScript/Main.ts

which generates - TypeScript\Main.js , TypeScript\Main.js.map

launch.json

   {
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Debug Test",
            "program": "${workspaceRoot}/TypeScript/Main.ts",
            "cwd": "${workspaceRoot}",
            "outFiles": ["${workspaceRoot}/JavaScript/**/*.js"],
            "sourceMaps": true
        }
    ]
}
