//const UglifyJsPlugin = require('uglify-js');
const isProd = process.argv.indexOf('-p') !== -1

//const bootstrapConfig = isProd ? bootstrapEntryPoints.prod : bootstrapEntryPoints.dev;

const cssDev = ['style-loader', 'css-loader', 'sass-loader'];
const cssProd = ExtractTextPlugin.extract({
                    fallback: 'style-loader',
                    use: ['css-loader', 'resolve-url-loader', 'sass-loader?sourceMap']

Same issue happened and solved by changing packages version.

• "ejs": "^2.7.4",
• "ejs-html-loader": "^4.0.1",
