I am new to the fiware eco-system and in the process of finding my way around.
I followed the Application-Mashup tutorial. Most of it works as described. I used the provided convenience-script to start up all containers and then followed the instructions to create and configure the widgets and operators.
I do get entities displayed, however, there appears to be no interactivity. Whenever I change the state in the device-monitor (switching on a lamp), my wirecloud dashboard does not update. Only when I refresh the browser the changed state can be seen.
I was expecting this to be updating immediately on its own via Context Broker Subscriptions. But it does not.
On the second part of the tutorial, that uses the NGSI-Source operator, I noticed that there is a field for Monitored NGSI Attributes. I suspect this is used to setup subscriptions. Now unfortunately, when I use this and put in an attribute name, I only get an error "Error creating subscription in the context broker server: Connection Error"
I tried to retrieve logs (via docker logs command), but did not find anything on the cause. All containers a running on my local machine, started with the provided script (that does run docker-compose) and are able to comunicate with each other.
I would appreciate any hints for getting the tutorial running.
Kind regards.
