Kogito's getById API returning null values for Enum fields (even though data is present in database).
This happens only when enum is part of nested class in the Main Process model.

Expected behavior

get and getById API should return values as saved :

{
"id":"string",
"a":{
"abc": "abc",
"classBvar":

{ "somevar":"var", "enumVar":"TEST1" }

}
}

Actual behavior

{
"id":"string",
"a":{
"abc": "abc",
"classBvar":

{ "somevar":"var", "enumVar":null }

}
}

How to Reproduce?

Scenario: 1) Add process variable of type class A in bpmn for any test process. and generate kogito code.
2) run post API for test process with following payload:
{
"a":{
"abc": "abc",
"classBvar":

{ "somevar":"var", "enumVar":"TEST1" }

}
}

Sample code:
public Class A

{ private String abc; private B classBvar; }

public class B

{ private String somevar; private TestEnum enumvar; }

public enum TestEnum

{ TEST1, TEST2 }
