The type Symfony\Contract\EventDispatcher\Event was not found. Maybe you did not declare it correctly or list all dependencies?

The expression return $dispatcher->dispatch($eventName, $event) also could return the type string which is incompatible with the documented return type Symfony\Component\EventDispatcher\Event|Symfony\Contract\EventDispatcher\Event.
