Hi all,

I'm serializing a custom class containing case object and other objects to JSON, and case's picklist serialize as this

"Status":{"value":"Finished"}

producing this error message when trying to deserialize

System.JSONException: Cannot deserialize instance of picklist from START_OBJECT value { or request may be missing a required field at [line:1, column:733]

Is it any kind of bug on the JSON Serialization or Deserialization?

When serializing Case records directly, picklists serialize in different way

TestJSON.cls

================================

List<Case> lc = new List<Case>();

lc.add(new Case(Status = 'Finished', External_ID__c = 'IDEXT_1'));

lc.add(new Case(Status = 'Finished', External_ID__c = 'IDEXT_2'));

lc.add(new Case(Status = 'Finished', External_ID__c = 'IDEXT_3'));

String js = JSON.serialize(lc);

System.debug(js);

Class code

global class EquipmentRemovalJob {
        public B1ActivationRequest activation;
        //There is some business methods
}
public class B1ActivationRequest {
        @InvocableVariable
        public Case request;
        @InvocableVariable
        public Contract_ATR__c contract;
        @InvocableVariable
        public CUPS__c cups;
}

Here you have a complete object JSON serialization
