Declaration of Drupal\entity_information\Routing\RouteSubscriber::getSubscribedEvents() must be compatible with Drupal\Core\Routing\RouteSubscriberBase::getSubscribedEvents(): array

Here's a patch.

I reviewed the above patch and it's resolved the issue. Before patch when i try to extend the module it gives fatal error and after applying patch the module enabled successfully. Additionally, I have attached before and after state screenshots for reference.

Thanks to you both. I will taak a look at the patch soon.

I can not reproduce this. Maybe it is fixed by the implemented coding standards fixes

I was able to reproduce this error in Drupal 10, looking at the Core RouteSubscriber libraries, adding ":array" in the function declaration solved my problem.

/**
* {@inheritdoc}
*/
public static function getSubscribedEvents(): array {
$events = parent::getSubscribedEvents();
$events[RoutingEvents::ALTER] = ['onAlterRoutes', 100];
return $events;
}

I leave the patch in the hands of whoever wants to do it.
Greetings.

I got this error on updating Drupal 9.5.11 to Drupal 10 with composer.

This is also in other modules, the same file.

To find all the affected files:
find ./ -type f -exec grep -Hni "getSubscribedEvents() {" {} \;

Shell command for 1 file:

sed -i 's/getSubscribedEvents() {/getSubscribedEvents():array {/g' ./modules/contrib/entity_usage_light/src/Routing/RouteSubscriber.php
