angular-seed: WebStorm (v2.3.1): Live reload after file change (html) does not work. SyntaxError: Unexpected token < in JSON at position 0

possible bug ? Windows 7, npm 4.0.1, node v6.8.1, TypeScript 2.0.10

Initial seed, nothing has been changed. Work-around here does not work.

That’s the Chrome Console:

VM661:1 Uncaught SyntaxError: Unexpected token < in JSON at position 0

    at http://localhost:5555/app/system-config.js:1:20(anonymous function) @ system-config.ts:2

    System.config(JSON.parse('<%= SYSTEM_CONFIG_DEV %>'));
    //# sourceMappingURL=system-config.js.map
