How to update EFF child column in REST API

Summary

Problem in updating the EFF child column using REST API

Content

Hi

I have the following payload where I have an eff attribute group MyEffChild with eff child field brand that needs to get updated. The json produces the following error:

Applying List binding LOV_ItemCatalogGroupValue with given set of values leads to no matching row for a row of type :ItemRestResource, key oracle.jbo.Key[1000 0002 1000 0002]

Can you please advise how to fix this problem?

Thank you and would appreciate any help.
