The method getObjectParents has a parameter includeObjectPaths. The objectPath is returned as a property. I would expect that if objectPath is a property, the filter determines if the property is returned or not. On the other hand getObjectParents() is the only method which returns this property. If objectPath is a property, I would also expect that each method returning properties can include this property. To avoid this confusion I would suggest not returning objectPath as a property but adding an additional field "path" to the response structure of getObjectParents.
