How to use %ValidateObject with %Dynamic properties?

 I am creating a class to validate JSON body of requests. When I use the method %ValidateObject to check errors in the object, if I define some properties with %DynamicObject or %DynamicArray and use the Required parameter, this method does not work, it ignores validation, only works with properties %String, %Integer etc.

Class test.Example Extends %RegisteredObject
{

Property id As %Integer [ Required ];

Property name As %String [ Required ];

Property fieldOptions As %DynamicArray [ Required ];

Method %OnNew(id As %Integer, name As %String, fieldOptions As %DynamicArray) As %Status [ Private, ServerOnly = 1 ]
{
    Set ..id = id
    Set ..name = name
    Set ..fieldOptions = fieldOptions
}

// fieldOptions is ""
Set test = ##class(test.Example).%New(1, "name", "")

Set obj = test.%ValidateObject()

Set message = $System.Status.GetOneErrorText(obj, 1)

Write message

// Return is "OK"
