[Fiware-tech-help] Fiware Orion MQTT notification not working (anymore)

[Guy Dillen]

Hello,
I don’t know where to look anymore, maybe you have an idea what’s going wrong?
I created an MQTT subscription on my Orion Context Broker:
{
"description": "Subscription to notify of all WaterQualityObserved changes",
"subject": {
    "entities": [{
        "idPattern": ".*",
        "type": "WaterQualityObserved"
    }],
     "condition": {
            "attrs": []
        }
},
"notification": {
    "mqtt": {
        "url": "mqtt://127.0.0.1:1883",
        "topic": "water-quality-observed-changed"
    }
}
}
I have both my Orion Context Broker and Mosquitto MQTT broker running locally in Docker containers. I get this when listing the subscriptions in my Orion CB:
[
{
    "id": "633bf12fe929777b6a60242b",
    "description": "MQTT subscription to notify of all WaterQualityObserved changes",
    "status": "active",
    "subject": {
        "entities": [
            {
                "idPattern": ".*",
                "type": "WaterQualityObserved"
            }
        ],
        "condition": {
            "attrs": []
        }
    },
    "notification": {
        "timesSent": 3,
        "lastNotification": "2022-10-04T08:47:55.000Z",
        "attrs": [],
        "onlyChangedAttrs": false,
        "attrsFormat": "normalized",
        "mqtt": {
            "url": "mqtt://127.0.0.1:1883",
            "topic": "water-quality-observed-changed",
            "qos": 0
        },
        "lastFailure": "2022-10-04T08:47:55.000Z",
        "failsCounter": 3,
        "covered": false
    }
}
]
As you can see “timesSent” augments when I PATCH the entity.
The strange thing is it worked before!
Any idea what I’m doing wrong?
Thanks.
Guy
