So I got this:
Controller "fos_rest.exception.twig_controller"
cannot be fetched from the container because it is private.
Did you forget to tag the service with "controller.service_arguments"
And naturally went looking for why the controller was not public. Turned out the controller was simply not defined at all. I think a simple:
cannot be fetched from the container because it is undefined or private
Might save some developer effort.
