EasyCorp\Bundle\EasyAdminBundle\Router\AdminUrlGenerator::setController(): Argument #1 ($crudControllerFqcn) must be of type string, null given

[richard4339]

EasyAdmin Version: >=4.21.0

Describe the bug

ErrorException: An exception has been thrown during the rendering of a template ("EasyCorp\Bundle\EasyAdminBundle\Router\AdminUrlGenerator::setController(): Argument #1 ($crudControllerFqcn) must be of type string, null given, called in /home/runner/work/user/user/vendor/twig/twig/src/Extension/CoreExtension.php on line 1871").

To Reproduce

public function testIndexPage2(): void
{
  SampleFactory::createMany(5);
  // retrieve the test user
  $testUser = UserFactory::createOne();

  // simulate $testUser being logged in
  $this->client->loginUser($testUser->_real());

  // this examples doesn't use security; in your application you may
  // need to ensure that the user is logged before the test
  $this->client->request(Request::METHOD_GET, $this->generateIndexUrl());
  static::assertResponseIsSuccessful();
}

(OPTIONAL) Additional context
Pretty URLs are on, I have a second identical test just pointing to a different entity/crud where this does not fail, and unlike #6715 this stops working with 4.21.0, though it seems very similar.

It might have been fixed by #6737.

I've upgraded and it's not fixed when i'm on a custom action WITH a search query in the

i.e

http://admin.localhost:8787/?crudAction=myCustomAction&crudControllerFqcn=App%5CController%5CAdmin%5CSomethingCrudController&entityId=365&query=x

This issue is still valid, same here.

I got excited for a bit because I thought it had been resolved for me as well, but realized late last night that the tests were still failing.
