It seems like you code against a specific sub-type and not the parent class Symfony\Component\EventDispatcher\Event as the method getDebugMessage() does only exist in the following sub-classes of Symfony\Component\EventDispatcher\Event: Sulu\Component\DocumentManager\Event\AbstractDocumentEvent, Sulu\Component\DocumentManager\Event\AbstractEvent, Sulu\Component\DocumentManager\Event\AbstractMappingEvent, Sulu\Component\DocumentManager\Event\ClearEvent, Sulu\Component\DocumentManager\Event\ConfigureOptionsEvent, Sulu\Component\DocumentManager\Event\CopyEvent, Sulu\Component\DocumentManager\Event\CreateEvent, Sulu\Component\DocumentManager\Event\FindEvent, Sulu\Component\DocumentManager\Event\FlushEvent, Sulu\Component\DocumentManager\Event\HydrateEvent, Sulu\Component\DocumentManager\Event\MetadataLoadEvent, Sulu\Component\DocumentManager\Event\MoveEvent, Sulu\Component\DocumentManager\Event\PersistEvent, Sulu\Component\DocumentManager\Event\QueryCreateBuilderEvent, Sulu\Component\DocumentManager\Event\QueryCreateEvent, Sulu\Component\DocumentManager\Event\QueryExecuteEvent, Sulu\Component\DocumentManager\Event\RefreshEvent, Sulu\Component\DocumentManager\Event\RemoveEvent, Sulu\Component\DocumentManager\Event\ReorderEvent. Maybe you want to instanceof check for one of these explicitly?
