Steps to reproduce

Exception after opening class

{type: "https://tools.ietf.org/html/rfc2616#section-10", title: "An error occurred", status: 500,…}
class
:
"TypeError"
detail
:
"Pimcore\Bundle\StudioBackendBundle\Class\Schema\ClassDefinition::__construct(): Argument #7 ($userOwner) must be of type int, null given, called in /var/www/html/vendor/pimcore/studio-backend-bundle/src/Class/Hydrator/ClassDefinitionHydrator.php on line 33"
status
:
500
title
:
"An error occurred"

The $data->getUserOwner() on the line 40 can return null

https://github.com/pimcore/studio-backend-bundle/blob/v2026.1.0/src/Class/Hydrator/ClassDefinitionHydrator.php#L40

but it is not nullable

https://github.com/pimcore/studio-backend-bundle/blob/v2026.1.0/src/Class/Schema/ClassDefinition.php#L78

So if class has no owner, the exception is thrown.

Actual Behavior

Exception if open class

Expected Behavior

No Exception if open class
