Я использую класс ReadNodeExample, чтобы попытаться получить информацию об узле сервера Kepware UA. Все в порядке, но BuildInfo, и я получаю следующее исключение:
19:00:32.723 [main] ERROR ClientExampleRunner - Error running client example: UaException: status=Bad_NotFound, message=A requested item was not found or a search operation ended without success.

И вот результат полного serverStatus:

Я не очень уверен, связана ли проблема с Kepware или с самим клиентом milo.
