Query caching breaks with Laravel 13 cache.serializable_classes

[gregory-claeyssens]

After upgrading to Laravel 13, query caching started failing because of the new cache.serializable_classes configuration:

https://laravel.com/docs/13.x/upgrade#cache-serializable_classes-configuration

When the restriction is enabled, cached queries can no longer be unserialized successfully. As a workaround, I had to disable the restriction entirely in config/cache.php:

'serializable_classes' => true,

Would it make sense to document this in the Lighthouse upgrade notes or query caching documentation? It would also be helpful to know which Lighthouse-related classes should be added to the serializable_classes allowlist.
