Cannot pass SearchFilterAction value in QueryPageOptions to backend when using HttpClient sending advanced query in WASM mode.

[MadLongTom]

This is a serialization issue associated with the builtin JSON serializer.

The QueryPageOptions class is designed to use List<IFilterAction> to store all advanced search criteria, but IFilterAction as an interface requires an explicitly specified implementation class to be handled by the built-in JSON serializer which is SearchFilterAction.

Given that SearchFilterAction is the only implementation of IFilterAction, should we add a Convertor & Attribute to IFilterAction that is enabled by default?
