System.ArgumentException when parsing the test webhook payload

Description of the Bug

I'm getting a System.ArgumentException when I read the Event object after serialization using either of the supported methods provided by the SDK.

var eventDto1 = ApiConfig.DeserializeObject<Event>(jsonString); var eventDto2 = new Event(jsonString);

This is the error:

Property accessor 'Index' on object 'ChargeBee.Models.Subscription+SubscriptionShippingAddress' threw the following exception:'The property index is not present!' System.Reflection.TargetInvocationException: Property accessor 'Index' on object 'ChargeBee.Models.Subscription+SubscriptionShippingAddress' threw the following exception:'The property index is not present!' ---> System.ArgumentException: The property index is not present! at ChargeBee.Internal.Resource.ThrowIfKeyMissed(String key) at ChargeBee.Internal.Resource.GetValue[T](String key, Boolean required) at ChargeBee.Models.Subscription.SubscriptionShippingAddress.get_Index() at System.RuntimeMethodHandle.InvokeMethod(Object target, Void** arguments, Signature sig, Boolean isConstructor) at System.Reflection.MethodBaseInvoker.InvokeWithNoArgs(Object obj, BindingFlags invokeAttr)

Steps to reproduce

Described above.

Expected Behavior

A shipping address with no index shouldn't throw an exception. Similarly, the test webhook function should provide a payload that doesn't throw exceptions when hooked up with the provided client.

In our context, we have interceptors that look into the object properties.
