Upgrading to drupal 10 and using openid_connect version "1.4" has \Symfony\Component\HttpKernel\Event\GetResponseEvent $event deprecation.
The website encountered an unexpected error. Please try again later.
TypeError: Drupal\*****\EventSubscriber\Redirect::onRequest(): Argument #1 ($event) must be of type Symfony\Component\HttpKernel\Event\GetResponseEvent, Symfony\Component\HttpKernel\Event\RequestEvent given in Drupal\*****\EventSubscriber\Redirect->onRequest() (line 40 of modules/custom/****/src/EventSubscriber/Redirect.php).
Replace "Symfony\Component\HttpKernel\Event\GetResponseEvent" ==> "Symfony\Component\HttpKernel\Event\RequestEvent"
Needs review
1.4
Code
There is no EventSubscriber\Redirect class in any version. Furthermore, the last line of that error message:
(line 40 of modules/custom/****/src/EventSubscriber/Redirect.php)
...suggests that this was an error in a custom module, not openid_connect.
