Uncaught Error injector unpr with angular after deployment

Question

I have a fairly simple Angular application that runs just fine on my dev machine  but is failing with this error message  in the browser console  after I deploy it   Uncaught Error    injector unpr  http   errors angularjs org undefined  injector unpr p0 tProvider 20 3C- 20t 20 3C- 20 24http 20 3C- 20 24compile  No other message besides that  It happens when the page first loads   I m running ASP NET MVC5  Angular 1 2RC3  and pushing to Azure via git    Googling hasn t turned up anything interesting    Any suggestions   EDIT   I m using TypeScript  and defining my dependencies with the  inject variable  e g    export class DashboardCtrl        public static  inject               scope             location            dashboardStorage              constructor          private  scope  IDashboardScope          private  location  ng ILocationService          private storage  IDashboardStorage              I believe that should  or is intended to  get around the local variable renaming problems that arise during minification and that can cause this error   That said  it clearly has something to do with the minification process  as when I set BundleTable EnableOptimizations   true on my dev machine  I can reproduce it

Add the  http   scope services in the controller fucntion  sometimes if they are missing these errors occur

If you have separated files for angular app resources directives and other stuff then you can just disable minification of your angular app bundle like this  use new Bundle   instead of ScriptBundle   in your bundle config file    bundles Add  new Bundle    bundles angular SomeBundleName   Include                    Content js angular Pages Web MainPage angularApi js                     Content js angular Pages Web MainPage angularApp js                     Content js angular Pages Web MainPage angularCtrl js       And angular app would appear in bundle unmodified

If you follow your link  it tells you that the error results from the  injector not being able to resolve your dependencies  This is a common issue with angular when the javascript gets minified uglified whatever you re doing to it for production   The issue is when you have e g  a controller   angular module  MyApp   controller  MyCtrl   function  scope   q         your code      The minification changes  scope and  q into random variables that doesn t tell angular what to inject  The solution is to declare your dependencies like this   angular module  MyApp      controller  MyCtrl      scope     q   function  scope   q         your code       That should fix your problem   Just to re-iterate  everything I ve said is at the link the error message provides to you

This problem occurs when the controller or directive are not specified as a array of dependencies and function  For example angular module  quot appName quot   directive  directiveName   function          return           restrict   AE           templateUrl   calender html           controller  function   scope                 scope selectThisOption   function                         some code                                      When minified The   scope  passed to the controller function is replaced by a single letter variable name   This will render angular clueless of the dependency   To avoid this pass the dependency name along with the function as a array  angular module  quot appName quot   directive  directiveName   function          return           restrict   AE           templateUrl   calender html          controller     scope   function   scope       lt -- difference              scope selectThisOption   function                         some code

I had the same problem but the issue was a different one  I was trying to create a service and pass  scope to it as a parameter  That s another way to get this error as the documentation of that link says      Attempting to inject a scope object into anything that s not a controller or a directive  for example a service  will also throw an Unknown provider   scopeProvider  lt -  scope error  This might happen if one mistakenly registers a controller as a service  ex     angular module  myModule               service  MyController      scope   function  scope               This controller throws an unknown provider error because            a scope object cannot be injected into a service

Ran into the same problem myself  but my controller definitions looked a little different than above   For controllers defined like this   function MyController  scope   http                   Just add a line after the declaration indicating which objects to inject when the controller is instantiated   function MyController  scope   http                 MyController  inject      scope     http      This makes it minification-safe
