error when creating a product variant with unique extra fields

[bieneart]

Bug

I'm using an "unique" extrafield to keep track of the url path for my onlineshop. Cloning/Duplicating deletes the value of the extrafield, but when I try to create a product variant, I get this error:

Duplicate entry 'tassen/lila-beeren' for key 'uk_product_extrafields_url_de'

Dolibarr Version

20.0.2

Environment PHP

8.2.7

Environment Database

MySQL 5.7.41

Steps to reproduce the behavior and expected behavior

1. Create an unique extrafield for products
2. Create a product with a value in this extrafield
3. Create a variant of this product
