Error when calling GetEntity or GetEntities for an Entity with an EntityReference property

[PixelDough]

I'm using source generation for my LDtk entities to have classes generated from their json objects, but when I try to get an object with an Entity reference as one of it's parameters, the game crashes with this error. If I remove the Entity Reference parameter, it works just fine.

System.NotSupportedException: JsonTypeInfo metadata for type 'LDtk.EntityReference' was not provided by TypeInfoResolver of type 'LDtk.LDtkJsonSourceGenerator'. If using source generation, ensure that all root types passed to the serializer have been annotated with 'JsonSerializableAttribute', along with any types that might be serialized polymorphically.
