> +Question:+
> Fiware - Orion Context Broker subscription V1, "conditions was supposed to be an array"
> +Description:+
> When trying to use STH to be able to store and retrieve data sent to OCB, I have a problem making the subscription.
> My problem is that the subscription creation goes well.
> When I create the subscription as following:
> POST /v1/contextSubscriptions HTTP/1.1
> Host: <cb_host>:1026
> Content-Type: application/json
> Fiware-Service: myService
> Fiware-ServicePath: /myServicePath
> Cache-Control: no-cache
> {
>   "entities": [
>     {
>       "type": "cameraSimple",
>       "isPattern": "true",
>       "id": "sensor03"
>     }
>   ],
>   "attributes": [ 
>     "class" 
>     ],
>   "reference": "http://<cb_host>:8666/notify",
>   "duration": "P1M",
>   "notifyConditions": [
>     {
>       "type": "ONCHANGE",
>       "condValues": [
>         "class"
>         ]
>     }
>   ],
>     "throttling": "PT5S"
> }
> I receive following answer:
> {
>   "subscribeResponse": {
>     "subscriptionId": "588b4f38e2066a50fa98df9b",
>     "duration": "P1M",
>     "throttling": "PT5S"
>   }

> but on the Fiware server, i see an error about the conditions in the terminal running the containers, and another one about the attributes:

> I use NGSI V1, as I suspect V2 is not yet supported for STH receiving NGSI V2 notifications regarding this issue. 
> Also i didn't find any documentation regarding "Getting historical raw context information" with NGSI V2, e.g on this page
