Warning: get_class() expects parameter 1 to be object

[OrangeTanguine]

With PHP7.0.30, we have a warning bug :
( ! ) Warning: get_class() expects parameter 1 to be object, null given in /usr/share/nginx/html/projectname/vendor/snowair/phalcon-debugbar/src/DataCollector/RouteCollector.php on line 59

Bug Line :
$result['Controller'] = get_class( $controller_instance = $dispatcher->getActiveController());

Fix :
$result['Controller'] = $dispatcher->getActiveController() != null ? get_class( $controller_instance = $dispatcher->getActiveController()) : $controller_instance ="";

Thks !
