Description
It seems payload to/from Kie Server when Domain Object POJO field starts with UpperCase have changed behaviour on 7.59.0.Final.
Here is a short highlight:
please notice the difference between the Identifier, Label and JSON payload. This used to work with 7.42.0.Final, just fine. In 7.59.0.Final the behaviour might have changed, and the payload is no longer compatible. Please notice I'm not coming up with the payload by hand, but this is dump from Kie Server Client Java API.
Follow steps to reproduce.
Creation of the project on BC, using 7.42.0.Final.
demo20210908applicant.zip
The project is a simple Rule that checks the content of Application.Applicant
Using a Maven based Kie Server Client Java API, to invoke the project once deployed on kie server:
demo20210908applicant-client.zip
We can notice the payload (as generated by the Kie Server Client Java API for JSON) uses lowercase for the properties.
We can notice the behaviour is as-expected, on the server receiving side, each Applicant of the family, has SSN and "US Citizen" fields correctly valorizes.
Relevant part of the LOG on client side:

Import the project on BC, using 7.59.0.Final.
Update the client application to 7.59.0.Final accordingly:
We can notice in log the client:

that both "SSN" and "US Citizen" valorization are not respected.
This COULD be related to JBPM-9784
