Class ExceptionRenderer
Exception Renderer.
Captures and handles all unhandled exceptions. Displays helpful framework errors when debug is true. When debug is false a ExceptionRenderer will render 404 or 500 errors. If an uncaught exception is thrown and it is a type that ExceptionHandler does not know about it will be treated as a 500 error.
Implementing application specific exception rendering
You can implement application specific exception handling by creating a subclass of
ExceptionRenderer and configure it to be the exceptionRenderer in config/error.php
Using a subclass of ExceptionRenderer
Using a subclass of ExceptionRenderer gives you full control over how Exceptions are rendered, you can configure your class in your config/app.php.
