AngularJS Error: [$injector:itkn] Incorrect injection token! Expected service name as string, got undefined

Question

Trying to run an Angular app containing this controller:

routerApp.controller('chartSettingsCtrl', ['$scope', '$timeout', 
 , function($scope, $timeout) { /* body omitted */ }

gives me the error:

Error: [$injector:itkn] Incorrect injection token! Expected service name as string, got undefined

What am I doing wrong?

Answer 1

The actual problem is that I had an extra , in the controller. When I changed that, it worked.

From

routerApp.controller('chartSettingsCtrl', ['$scope', '$timeout',
 , function($scope, $timeout) {

To

routerApp.controller('chartSettingsCtrl', ['$scope', '$timeout',
 function($scope, $timeout) {
