Remark if using > CakePHP 3.3.0 and using middleware

If you utilise CakePHP middlewares from https://book.cakephp.org/3.0/en/controllers/middleware.html

You can use the supplied NewRelicErrorHandlerMiddleware placed in NewRelic\Middleware\NewRelicErrorHandlerMiddleware which extends the built in Cake\Error\Middleware\ErrorHandlerMiddleware. By using this you'll get the NewRelic working and have default CakePHP behavior.

Example:

<?php

namespace App;

use Cake\Http\BaseApplication;
use Cake\Routing\Middleware\AssetMiddleware;
use Cake\Routing\Middleware\RoutingMiddleware;

/**
 * Application setup class.
 *
 * This defines the bootstrapping logic and middleware layers you
 * want to use in your application.
 */
class Application extends BaseApplication
{
    /**
     * Setup the middleware your application will use.
     *
     * @param \Cake\Http\MiddlewareQueue $middleware The middleware queue to setup.
     * @return \Cake\Http\MiddlewareQueue The updated middleware.
     */
    public function middleware($middleware)
    {
        $middleware
            // Catch any exceptions in the lower layers,
            // and make an error page/response
            ->add(\NewRelic\Middleware\NewRelicErrorHandlerMiddleware::class)
            // Handle plugin/theme assets like CakePHP normally does.
            ->add(AssetMiddleware::class)
            // Apply routing
            ->add(RoutingMiddleware::class);
	    
        return $middleware;
    }
}
