My Plugins:

  plugins: [
    new webpack.DefinePlugin({
      'process.env.NODE_ENV': JSON.stringify(process.env.NODE_ENV || 'production')
    }),

    new ExtractTextPlugin('style.css'),

    new BundleAnalyzerPlugin({
      analyzerMode: process.env.OPEN_ANALYZER === 'true' ? 'server' : 'disabled',
      openAnalyzer: process.env.OPEN_ANALYZER === 'true'
    }),
    
    new JavaScriptObfuscator({
      disableConsoleOutput: false,
      rotateUnicodeArray: true,
      encodeUnicodeLiterals: true
    }),

I’m not using devtool to generate sourcemaps. I’m not sure where to begin with debugging this. Any thoughts? Thanks very much for reading.
