Возникли проблемы с подпиской оператора Source NGSI Wirecloud на собственный экземпляр Orion.Я могу подтвердить, что все настройки оператора верны, но не смог понять ход этой ошибки:
Error creating subscription in the context broker server: Connection Error
Настройки:
NGSI server URL: http://193.136.xx.xx:53149/
NGSI proxy URL: http://127.0.0.1:3000
FIWARE-service: urbansense
FIWARE-servicePath: /basic
NGSI entity types: WeatherObserved
Monitored NGSI attributes: location, temperature, relativeHumidity
#all other options empty/uncheck
Чтобы подтвердить, что указанный объект и атрибутыфактически доступно:
$ curl 193.136.xx.xx:53149/v2/entities -H 'fiware-service: urbansense' -H 'fiware-servicepath: /basic'
