%ToJSON() is only defined on objects extending %DynamicAbstractObject.
For example:

SAMPLES>s obj={"test":"42"}

To serialize arbitrary %Persistent/%Registered objects you'll have to use altJSONProvider
for example:

SAMPLES>s p=##class(Sample.Person).%OpenId(1)
SAMPLES>d ##class("%ZEN.Auxiliary.altJSONProvider").%WriteJSONFromObject(,.p)
