js-beautify has been updated to version 1.2.0 the current version of this task is very outdated. Also updated grunt to version 0.4.1 since this version has a very importat patch added. On options removed " " from config since it is a common standard on grunt tasks to not have any quotes on config.
this will also solve this issue:
Updated to fit new version of js-beautify
Will publish to npm after sanity check
