Question:
FIWARE Orion Context Broker API V2 - accumulator-server.py

Description:
When I try to create a subscription using the next query:

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": [
>

> ],
> "condition":

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

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

An error occurs:

• About to connect() to localhost port 1026 (#0)
• Trying ::1... connected

• Connection #0 to host localhost left intact
• Closing connection #0 {"error":"BadRequest","description":"no condition attributes specified"}

However, if I make the query using the V1 of the API all work right. I do not know why. Please help me!
