I get
[request] Uncaught PHP Exception Symfony\Component\Debug\Exception\ContextErrorException: "Catchable Fatal Error: Object of class Doctrine\ORM\Cache\AssociationCacheEntry could not be converted to string" at /var/www/Youmiam/vendor/doctrine/orm/lib/Doctrine/ORM/UnitOfWork.php line 2676
When I try to get an object for the first time, but it only happens when I get an object with an EAGER association and the problem appears when I installed the second level cache.

If it could help, there is my code :
Association :

     /**
     * @ORM\ManyToOne(targetEntity="Acme\MyBundle\Entity\Product", inversedBy="quantities", fetch="EAGER")
     * @ORM\JoinColumn(name="product")
     * @ORM\Cache(usage="NONSTRICT_READ_WRITE")
     */
     private $product;

On the top of this class :
* @ORM\Cache(usage="NONSTRICT_READ_WRITE", region="region_quantity"))

On the top of the other class :
* @ORM\Cache(usage="NONSTRICT_READ_WRITE", region="region_product"))

My config :

snc_redis:
    # configure predis as client
    clients:
        doctrine:
            type: predis
            alias: cache_client

Thanks in advance.

@BourotBenjamin looks like this is a duplicate of #5578 and as mentioned there we weren't able to reproduce it on the latest version of master.

So I'm closing this issue.
