Issue in minifying the js bundle files

[mianRafay]

Hi, I am facing the issue in minifying of js files.
Here is my code :

const path = require("path")
const webpack = require("webpack")
const UglifyJsPlugin = require("uglifyjs-webpack-plugin")
const uglifyJS = require("uglify-js");
const MergeIntoSingleFilePlugin = require('webpack-merge-and-include-globally');
const fs = require('fs');

module.exports = {
entry: {

    controllers: [
        "./wwwroot/docs/controllers/accountCtrl.js",

Here is the error:

[markshapiro]

can you try to use new AddAssetPlugin('designer.bundle.js', '') to isolate the problem in order to know whether the plugin throws the error?

Thanks for the reply. The problem was with the uglify js plugin. It's all good now. 👍
