| Http Exception Handler
|--------------------------------------------------------------------------

| AdonisJs will forward all exceptions occurred during an HTTP request to
| the following class. You can learn more about exception handling by
| reading docs.
|
| The exception handler extends a base `HttpExceptionHandler` which is not
| mandatory, however it can do lot of heavy lifting to handle the errors
| properly.
