setJsonPropertyNull
setJsonPropertyNull(name: StringUtf8);
The setJsonPropertyNull method of the JadeJsonObject class sets the JSON property with the name specified in the name parameter to a null value. If the property does not exist, a property with that name is created and set to a null value. If the property already exists but it is not of the JSON null type, its type is changed to the JSON null type.
