• VSCode Version: 1.2.1
• OS Version: Windows 10

Steps to Reproduce:

1 - If I, in node.js 6.6, write (resp. have transpiled from TypeScript) a class like that:

 class Table {
    constructor(args) {
         this._rows = new Proxy({ test: 42 }, {});
    }
 }

2 - And then instantiate it like this:

var table = new Table();

3 - When I debug in Visual Studio Code and I want to watch the var table I always have

Internal error: illegal access

written there, meaning I can not watch table or any of its properties.

The same thing works perfectly fine in Chrome.

I have raised this on Stackoverflow:
