Reference error: WebpackJsonp not defined

Question

Converted my existing Angular 2 project into electron base cross platform than I installed electron-forge start development tools for development to simple easy way to package.

A command to launch app : electron-forge start

Unlikely returned an reference error "WebpackJsonp not defined" in error popup.

I found one of Stackoverflow answered to put your vendor.js before main.js but unfortunately it's not work in my case.
