@fumblehool How did you solved it?

fumblehool commented 6 years ago

@vtni I was trying to extend functionality of an older project. It used uglifyjs-webpack-plugin@1.1.4. So I had to downgrade webpack to v3 and upgrade uglifyjs-webpack-plugin@1.1.4 to uglifyjs-webpack-plugin@1.3.0 As pointed out by @evilebottnawi , problem was in uglify-js. This problem is fixed in uglify-js@3.4.3
