API getMembers() with parentId property is not working

[avalko]

Hello,

In the model I have a Product dimension with hierarchy:

In the story I want to read only root members (Product classes) using script API. I wrote a simple code and specified a parentId property to retrieve such members:

But unfortunately this script returns all the elements of the Product dimension::

Also, I want to mention that in previous versions this code worked. Now I am on 2024.15. Why is it not working now? Maybe I am doing something wrong?

Best Regards,

Anton
