There s also another way this could happen   In my app I have a main module that takes care of the ui-router state management  config  and things like that  The actual functionality is all defined in other modules   I had defined a module  angular module  account     services       that had a controller  DashboardController  in it  but had forgotten to inject it into the main module where I had a state that referenced the DashboardController   Since the DashboardController wasn t available because of the missing injection  it threw this error

I had the same error in a demo app that was concerned with security and login state   None of the other solutions helped  but simply opening a new anonymous browser window did the trick     Basically  there were cookies and tokens left from a previous version of the app which put AngularJS in a state that it was never supposed to reach   Hence the areq assertions failed

I ve gotten that error twice   1  When I wrote   var app   module  flapperNews          instead of   var app   angular module  flapperNews          2  When I copy and pasted some html  and the controller name in the html did not exactly match the controller name in my app js file  for instance   index html    lt script src  app js  gt  lt  script gt           lt body ng-app  flapperNews  ng-controller  MainCtrl  gt    app js   var app   angular module  flapperNews         app controller  MyCtrl          In the html  the controller name is  MainCtrl   and in the js I used the name  MyCtrl      There is actually an error message embedded in the error url      Error   ng areq    http   errors angularjs org 1 3 2 ng areq p0 MainCtrl amp p1 not 20a 20function 2C 20got 20undefined   Here it is without the hieroglyphics      MainCtrl not a function got undefined   In other words   There is no function named MainCtrl   Check your spelling

I know this sounds stupid  but don t see it on here yet     I had this error caused by forgetting the closing bracket on a function and its associated semi-colon since it was anonymous assigned to a var at the end of my controller   It appears that many issues with the controller  whether caused by injection error  syntax  etc   cause this error to appear

I got this same error when I included the entire controller file name in the Routes like this   app config function  routeProvider         routeProvider       when                 templateUrl   home html           controller   mainController js               when   portfolio              templateUrl   portfolio html           controller   mainController js               When it should be   app config function  routeProvider         routeProvider       when                 templateUrl   home html           controller   mainController               when   portfolio              templateUrl   portfolio html           controller   mainController               Angular takes certain things you name like the app and controller and expounds on them in directives and across your app  take care to name everything consistently and check for this when debugging

I had done everything right other than setting controller in  stateProvider  I used filename rather than variable name    Following code is wrong   formApp config function  stateProvider   urlRouterProvider          stateProvider          state  management                 url    management               templateUrl   Views management html               controller   Controllers ManagementController js                and this is the right approach   formApp config function  stateProvider   urlRouterProvider          stateProvider          state  management                 url    management               templateUrl   Views management html               controller   ManagementController                Make sure you noticed      controller   ManagementController    And for those who are curious about my controller file ManagementController js  it looks like the this   formApp controller  ManagementController      scope     http     filter     state  function scope  http  filter  state        scope testFunc   function             scope managementMsg     Controller Works Fine                  For those who want a quick-start angular skeleton for above example check this link https   github com zaferfatih angular skeleton

The error will be seen when your controller could not be found in the application   You need to make sure that you are correct using values in ng-app and ng-controller directives

Check the name of your angular module   what is the name of your module in your app js   In your TransportersController  you have   angular module  mean transporters     and in your TransportersService you have   angular module  transporterService         You probably want to reference the same module in each   angular module  myApp

I have made a stupid mistake and wasted lot of time so adding this answer over here so that it helps someone  I was incorrectly adding the  scope variable dependency  was adding it without single quotes   for example what i was doing was something like this  angular module  myApp      controller  akshay    scope    where the desired syntax is like this  angular module  myApp      controller  akshay     scope

I ran into this issue when I had defined the module in the Angular controller but neglected to set the app name in my HTML file  For example    lt html ng-app gt    instead of the correct    lt html ng-app  myApp  gt    when I had defined something like   angular module  myApp       controller       and referenced it in my HTML file
