When upgrading to Doctrine 3, Symfony return this error:
Tree object class: App\Entity<name of Entity> must have tree metadata at this point

Minimal repository with the bug

Steps to reproduce

$this->em->getConfiguration()->addCustomHydrationMode('tree', \Gedmo\Tree\Hydrator\ORM\TreeObjectHydrator::class);       
 $repo = $this->em->getRepository(\App\Entity\<nameOfEntity>::class);       

Expected results

The result of the query (it works with doctrine v2)

Actual results

Exception: Tree object class: App\Entity<name of Entity> must have tree metadata at this point

You have the tree listener enabled, correct?

What type of mapping are you using for your entity? ORM 3.x doesn't support annotations, so if you've been using those, then you'll need to update to use attributes.

Your output shows that doctrine/annotations is installed. This library will default to using annotations for its internal metadata reader when that package is installed for B/C reasons unless you provide a reader service to the listeners, otherwise it will try defaulting to the attribute reader. If you're using StofDoctrineExtensionsBundle, the 1.12 release adds support for automatically using the attribute reader when needed; if you aren't using it, https://github.com/doctrine-extensions/DoctrineExtensions/blob/main/doc/symfony.md#doctrine-extension-listener-services can give you an idea on how to configure your services to provide the attribute reader.
