The NPE in TaxonNodeServiceImpl.dto has been fixed. Please review and check that controller returns correct http error (404 ?) when null is returned.

Your fix is correct.

I added a further null check in the controller method so that the the service responds with the correct http code in case the uuid does not exists.
