0.31 and 0.32 releases are broken by UglifyJS 3.X

[ddemid]

It silently fails to minify the js and uploads empty file to s3.

Since 0.31 you've upgraded to uglifyjs 3.X in package.json, which is being incorrectly used.

var final_code = uglify.minify(results, { fromString: true, output: { comments: /license/ } }).code;

gives undefined as a result. And since you aren't checking the error property, it fails silently.

The real error message is:

"fromString" is not a supported option node
