It seems like $config->get('eventListener') of type * is incompatible with the declared type array<integer,object<Faulancer\Event\AbstractListener>> of property $listener.

            self::$instance = new self();

        }

        return self::$instance;

                if ($typeName === $event::NAME) {

                    if (!class_exists($listener)) {
                        continue;

                    /** @var AbstractListener $listener */
                    $listener = new $listener();
                    $listener->create();
                    $callback = $listener->getCallback();
                    $callback->execute($event);

The method execute cannot be called on $callback (of type callable).

                }

            }
