appharbor에서 응용 프로그램 시작시 Ninject가 충돌 함

Question

appharbor에 배포 된 MVC 3 프로젝트에서 Ninject를 사용하고 있습니다. 응용 프로그램이 시작될 때 예외가 발생하고 Ninject가 원인 인 것처럼 보였으 나 거기에서 어떤 대답도 찾을 수 없다는 것을 알았습니다. - 그래서 제발 도와주세요. :)

완전한 예외를 추가하려고합니다. 여기 :

Server Error in '/' Application. 

Object reference not set to an instance of an object. 

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

페이지를 다시로드하면 예외가 사라집니다. 이것은 필터 Ninject에 사용하여 함께 할 수있는 뭔가가있을 수 있습니다 :

this.BindFilter<AdminAuthorizationAttribute>(FilterScope.Controller, -100) 
    .When((context, ad) => context.RouteData.DataTokens["area"] != null && 
      ((string)context.RouteData.DataTokens["area"]).ToLower() == "admin" && 
      ((string)context.RouteData.Values["controller"]).ToLower() != "login"); 

Answer 1

문제가 Ninject에 의해 발생되지 않습니다. 그것은 NewRelic.Agent입니다 .Core.AgentShim (AppHarbor에서 사용)이 범인입니다.

stacktrace를 살펴 보았지만 Ninject의 자동 확장 기능을 비활성화하고 수동으로로드하여이 문제를 해결할 수 있다고 생각합니다.

var kernel = new StandardKernel(new NinjectSettings { LoadExtensions = false }) 
kernel.Load(new Ninject.Web.Mvc.MvcModule()); // same for all other extension modules 

Answer 2

임시로 New Relic 애드온을 비활성화하고 AppHarbor 서버에서 새 유적 에이전트를 제거했습니다. 플랫폼에서 실행되는 응용 프로그램에서 더 이상 문제를 일으키지 않으면 New Relic을 다시 추가합니다.
