input contains a "__type" property that indicates a custom type, but the result of deserializing the corresponding JSON string cannot be assigned to the expected target type.

-or-

input contains a "__type" property that indicates either Object or a non-instantiable type (for example, an abstract type or an interface).

An attempt was made to convert a JSON array to an array-like managed type that is not supported for use as a JSON deserialization target.
