Clean installation on PHP8.3. Using the following packages:

"doctrine/doctrine-orm-module": "^6.1",
"doctrine/doctrine-module": "^6.1",
"laminas/laminas-cache":"^3.12",
"laminas/laminas-cache-storage-adapter-redis":"^2.9"

Configuration:

   ...
    'service_manager' => [

            'Service\Redis' => Service\Factory\RedisFactory::class,
        ],

“Service/Redis” → RedisFactory.php

<?php
namespace Application\Service\Factory;
use Laminas\Cache\Storage\Adapter\Redis;
use Psr\Container\ContainerInterface;
class RedisFactory
{
    public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
    {
        $redis = new Redis([
            'server' => ['host' => '127.0.0.1', 'port' => 6379],
        ]);

        return $redis;
    }
}

Works fine. Connecting to the Redis instance and creating the keys. However, the keys are stored as “Array” and “Object” as string and the query is always executed instead of fetching from the cache (which I don’t think the stored array/object strings will work anyway).

laminas-doctrine-cache

Could you help me figure out what I might be doing wrong?
Or, do you have any recommendations for a recent Doctrine/Laminas/Cache implementation (aside from the Doctrine ORM Module for Laminas documentation, which works with v5 but not fully with v6)?

Thanks in advance.

I found the solution by step by step debugging and posted it in StackOverflow.

The short versions is the “lib_options” option and the “serializer” different than the ORM 5. You can find the details over there.

Hopefully my question helps someone trying to set up cache with Doctrine ORM 6 and Laminas Cache 3. Perhaps the documentation could be also updated with more information - even removing the annotation driver class which is deprecated etc.
