Solution

  • I think you need to add this to your pipeline:

    plug Guardian.Plug.Pipeline, module: App.Guardian, error_handler: App.Web.SessionController

    You should also check that you're using the same version of Guardian that the tutorial is using. They introduced many changes to the 1.0 release of Guardian compared to previous versions of the library.
