Error 500, when robot open Phalcon micro app

Hello! Sory my English.

I have Phalcon micro application. When I open my site in a browser, Nginx shows code 200 and no errors in log. But, when robot open my site, Nginx show code 500: ``` HTTP/1.1 500 Internal Server Error Server: nginx Date: Tue, 30 May 2017 08:12:58 GMT Content-Type: text/html; charset=UTF-8 Connection: keep-alive ```

Access log: ``` "HEAD / HTTP/1.1" 500 - ```

Error log: ``` PHP Fatal error: Uncaught Phalcon\Mvc\Micro\Exception: Not-Found handler is not callable or is not defined in /home/srv/http/projects/lorhealth.localhost/public/index.php:19\nStack trace:\n#0 /home/srv/http/projects/lorhealth.localhost/public/index.php(19): Phalcon\Mvc\Micro->handle()\n#1 {main}\n thrown in /home/srv/http/projects/lorhealth.localhost/public/index.php on line 9 ```

public/index.php: ```php <?php errorreporting(EALL); define('ROOTPATH', DIR . '/../'); include ROOTPATH . 'app/config/config.php'; include ROOTPATH . 'app/config/loader.php'; $app = new Phalcon\Mvc\Micro(); include ROOTPATH . 'app/config/services.php'; include ROOT_PATH . 'app/config/routes.php'; $app->handle(); ```

What could be the problem?

Robots are making HEAD / HTTP/1.1 requests. Your Micro does not have route / controller to handle HEAD routes / requests.

That's why you can access it with a browser, as browsers make GET requests.

If you're using MicroCollection class for routes, take a look at: https://docs.phalconphp.com/en/latest/api/Phalcon_Mvc_Micro_Collection.html
