> +Question:+
> Fiware - Orion Context Broker subscription not sent to STH, "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:

> Note:
> 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
> I use Docker-machine with a single Debian 8 VM running on Fiware-Lab with following images:
> mongodb:
> image: mongo:2.6
> hostname: mongodb
> container_name: mongodb
> command: --smallfiles
> orion:
> image: fiware/orion:develop
> hostname: orion
> container_name: orion
> links:
> - mongodb
> expose:
> - "1026"
> ports:
> - "1026:1026"
> command: -dbhost mongodb
> fiware-sth-comet:
> image: telefonicaiot/fiware-sth-comet
> links:
> - mongodb
> ports:
> - "8666:8666"
> environment:
> - STH_HOST=0.0.0.0
> - DB_URI=mongodb:27017
> EDIT 1: After removing the "develop" of Orion Docker image I am now running verison "1.6.0-next" of Orion, and I don't have any more the runtime error. Still, I can't get any historical value of the attributes of the entity. I must be doing some error in the request, but I don't know where.
> Now my docker-compose file looks like this:
> mongo:
> image: mongo:3.2
> command: --nojournal
> orion:
> image: fiware/orion
> links:
> - mongo
> ports:
> - "1026:1026"

> - DB_URI=mongo:27017
> cygnus:

> EDIT 2: Following @GermánTorodelValle advice, I try to simulate a notification to the STH container like the CB would send:
> curl -X POST -H "Accept: application/json" -H "Content-Type: application/json" -H "Fiware-Service: myService" -H "Fiware-ServicePath: /myServicePath" -d '{
