Zend Framework 2.x Learn ZF2 by Example : Unable to render template

Getting to the MVC portion of the book and ran into an error. On page 59 it shows you how to manually include a template to aid debugging. I ran into this error when trying to see my changes.

Fatal error: Uncaught exception 'Zend\View\Exception\RuntimeException' with message 'Zend\View\Renderer\PhpRenderer::render: Unable to render template "debug/layout/sidebar"; resolver could not resolve to a file' in /Volumes/zend_framework/learnzf2/vendor/zendframework/zendframework/library/Zend/View/Renderer/PhpRenderer.php:498 Stack trace: #0 /Volumes/zend_framework/learnzf2/vendor/zendframework/zendframework/library/Zend/View/View.php(205): Zend\View\Renderer\PhpRenderer->render(Object(Zend\View\Model\ViewModel)) #1 /Volumes/zend_framework/learnzf2/vendor/zendframework/zendframework/library/Zend/Mvc/View/Http/DefaultRenderingStrategy.php(102): Zend\View\View->render(Object(Zend\View\Model\ViewModel)) #2 [internal function]: Zend\Mvc\View\Http\DefaultRenderingStrategy->render(Object(Zend\Mvc\MvcEvent)) #3 /Volumes/zend_framework/learnzf2/vendor/zendframework/zendframework/library/Zend/EventManager/EventManager.php(468): call_user_func(Array, Object(Zend\Mvc\MvcEvent)) #4 /Volumes/zend_framework/learnzf2/vendor/zendframe in /Volumes/zend_framework/learnzf2/vendor/zendframework/zendframework/library/Zend/View/Renderer/PhpRenderer.php on line 498

Page 58 talks about the way templates are included. The middle of the page shows a config option called 'template_path_stack'. This is the path the PhpRender uses to find manually included templates. There is a similar line in the Application module.config.php. I thought this would be imported into the master config but that didn't happen. You have to add this.
