This error seems to be due to the uglify options needing to be formatted like this:

uglify: {
     uglifyOptions: {
         output: {
             comments: false 
         }
     }
 }

This can be seen in the default mix config file here: https://github.com/JeffreyWay/laravel-mix/blob/master/src/config.js#L286
