[max-zhang78]

Affected Version

2025.4 - LTS

Affected capability

Data Objects

Steps to reproduce

studio ui
If the class of object is changed from Product to ProductDemo, the following interface will report an error

Affected api
pimcore-studio/api/data-object/grid/available-columns?classId=1&folderId=5957
pimcore-studio/api/data-object/grid/available-columns-for-relation?classld=1&relationField=Component
pimcore-studio/api/data-object/grid/available-columns-for-relation?classld=18relationField=Bundle
pimcore-studio/api/data-object/grid/available-columns?classld=1&relationField=Accessories
pimcore-studio/api/data-object/grid/available-columns?classld=1&relationField=Successor
pimcore-studio/api/data-object/grid/available-columns?classld=1&relationField=Predecessor

The temporary fix method is to change the Product in var/classes/definition-ProductDemo. php to a Product Demo

I have a question. If there are some custom elements in var/config/object_custom_layouts/* yaml, will it affect the generated definition-ProductDemo. php file?
If there is no impact, it is more certain that it is a bug

executing bin/console pimcore: build: classes still has issues
