У меня есть доступ к моим облачным базам данных, но передача им данных в команде вставки не обновляет их. Записи остаются на нуле.
Я просмотрел документацию по couchdb с профессионалом, и у меня есть видео-свидетельство curl с командами couchdb, которые получают доступ к моему экземпляру bluemix cloudant со всеми учетными данными, отображаемыми на экране учетных данных; однако команды curl, измененные с помощью couch db, не обновляют базу данных. Записи остаются на нуле.
Я попытался обновить базы данных двух разных облачных экземпляров на двух разных учетных записях bluemix lite, используя curl и node-red. Результаты одинаковы.
Прилагается модель потока, которую я использую с измененными узлами-облаками, чтобы учетные данные и фокус базы данных соответствовали моей ситуации (это было первое, что я трижды проверил).

Не было сообщений об ошибках. Узел отладки, присоединенный к моему узлу, генерирующему объекты http, возвратил полный объект json.
Я ожидаю, что смогу получить доступ и обновить мои облачные базы данных.
