ngsi list subscriptions without "service"

[dkastl]

Problem

I'm not sure this is a bug or intentional, but I experienced some unexpected behaviour trying to list subscriptions without specifying "service".

How to reproduce

I tried several released of FIWARE-BigBang, because I thought it worked as expected in previous releases. But this was actually not the case.

After installation with the default config.sh, run:

export FIWARE_TOKEN=sample_token
export BROKER_URL=https://example.com/v2/subscriptions

# Create a Subscription with Service and ServicePath
curl -X POST \
  $BROKER_URL \
  -H "Content-Type: application/json" \
  -H "X-Auth-Token: $FIWARE_TOKEN" \
  -H "Fiware-Service: myservice" \
  -H "Fiware-ServicePath: /mysubservice" \
  -d '{
    "description": "Temperature subscription with Service and ServicePath",
    "subject": {
      "entities": [{"idPattern": ".*", "type": "Room"}],
      "condition": {"attrs": ["temperature"]}
    },
    "notification": {
      "http": {
        "url": "http://my.listener.com/notify"
      },
      "attrs": ["temperature"]
    },
    "expires": "2024-12-31T14:00:00.00Z",
    "throttling": 5
  }'

# Create a Subscription without Service and ServicePath
curl -X POST \
  $BROKER_URL \
  -H "Content-Type: application/json" \
  -H "X-Auth-Token: $FIWARE_TOKEN" \
  -d '{
    "description": "Humidity subscription without Service and ServicePath",
    "subject": {
      "entities": [{"idPattern": ".*", "type": "Room"}],
      "condition": {"attrs": ["humidity"]}
    },
    "notification": {
      "http": {
        "url": "http://my.listener.com/notify"
      },
      "attrs": ["humidity"]
    },
    "expires": "2024-12-31T14:00:00.00Z",
    "throttling": 5
  }'

# Request the List of Subscriptions
curl -X GET \
  $BROKER_URL \
  -H "X-Auth-Token: $FIWARE_TOKEN" \
  -H "Fiware-Service: myservice" \
  -H "Fiware-ServicePath: /mysubservice"

curl -X GET \
  $BROKER_URL \
  -H "X-Auth-Token: $FIWARE_TOKEN"

This returns the subscriptions as expected.

Now using NGSI-GO

# Request "myservice"
$ ngsi list subscriptions --verbose --service myservice
667448ae33211b06ef0c241e active 2024-12-31T14:00:00.000Z Temperature subscription with Service and ServicePath

# Request without "--service"
$ ngsi list subscriptions --verbose
667448ae33211b06ef0c241e active 2024-12-31T14:00:00.000Z Temperature subscription with Service and ServicePath

So whether --service myservice is provided as argument or not, the same subscription ("with Service") is returned.

I was able to request the subscription "without Service" like this

$ ngsi list subscriptions --service "" --verbose
667448b733211b06ef0c241f active 2024-12-31T14:00:00.000Z Humidity subscription without Service and ServicePath

Expected Behaviour

I would expect NGSI GO to return the same subscriptions as if calling the API with cURL.

• When --service <service_name> parameter is provided, list all subscriptions of that service
• When the --service parameter is not set, list all subscriptions of the "default" tenant
