      Question:
      FIWARE - Orion Context Broker - Cannot create subscription - Callback is missing

      Description:
      I'm working with the Orion Context Broker and I'm trying to add a new subscription but I'm getting an error that the callback is missing even though I have provided one.

      Here are the entities that I have

      $ curl localhost:1026/v2/entities -s -S --header 'Accept: application/json' | python -mjson.tool
      [
      {
      "id": "Room1",
      "pressure": {
      "metadata": {},
      "type": "Integer",
      "value": 720
      },
      "temperature": {
      "metadata": {},
      "type": "Float",
      "value": 23
      },
      "type": "Room"
      },
      {
      "id": "Room2",
      "pressure": {
      "metadata": {},
      "type": "Integer",
      "value": 711
      },
      "temperature": {
      "metadata": {},
      "type": "Float",
      "value": 21
      },
      "type": "Room"
      }
      ]

      And here is the call to create a new subscription and subsequent error:

      $ curl -v localhost:1026/v2/subscriptions -s -S --header 'Content-Type: application/json' \
      > d @ <<EOF
      > {
      > "description": "A subscription to get info about Room1",
      > "subject": {
      > "entities": [
      >

      { > "id": "Room1", > "type": "Room" > }

      > ],
      > "condition":

      { > "attributes": ["temperature"] > }

      > },
      > "notification": {
      > "http":

      { > "url": "http://localhost:1028/accumulate" > }

      ,
      > "attrs": [
      > "temperature",
      > "pressure"
      > ]
      > },
      > "expires": "2040-01-01T14:00:00.00Z",
      > "throttling": 5
      > }
      > EOF
