Autofac and ASP .Net MVC 4 Web API

I am using Autofac for IoC in my ASP .Net MVC 4 project. Autofac is having some trouble initializing the repository and passing it to the API Controller.

I am sure I am missing something in my configuration.

Here is the error I get when I navigate to: https://localhost:44305/api/integration

<Error>
    <Message>An error has occurred.</Message>
