OrderLine CustomField with Translatable Custom Entity

[cdiban-loads]

Hi Everyone!

I'm seeking help with a use case regarding relation type custom fields in order lines but with translations. My entity has translation code and other properties but when I try to view the order detail I have an error that says "Cannot return null for non-nullable field..." I changed my ApiExtension to nullable, its work but I can't get the properties with the data.

Is it possible to fix this implementation? I'm doing something wrong?

Thanks!

Hi,
I think this might be related to #1664. Can you provide a minimal reproduction of the issue?
