Unable to minify JS

Before implementing Firebase authentication this JS file successfully minifyed without any problems.

The file works without any problems when using the none-midifyed version, I'm unable to test the minifyed version as Atom will not allow me to minify and save due to the following error (See attached)!

I'm using and following Scotch.io's advice: https://scotch.io/tutorials/declaring-angularjs-modules-for-minification

Any pointers/advice would be great!

Controller JS

var fbcontrollers = angular.module('fbcontrollers', []);
fbcontrollers.controller('authCtrl', ['$scope', 'Auth', '$location', function($scope, Auth, $location) {

I am pretty sure the problem is connected with the use of catch. Note that catch is a keyword in javascript, used in exception (error) handling. Promises use catch as a method name and that's a bit of a collision. In general it's safer to use it indirectly:

}).then(function(...) {
   ...
})['catch'](function(error) {
   ...
});

The same applies to the finally keyword.
