> +Question:+
> Orion subscriptions that never receive changes
> +Description:+
> I'm having a problem with some entities to make the subscriptions. The subcriptions are well done (orion responds ok. Status 201) but the url subscribed never receive any update.
> I have fiware-orion launched with docker over a Centos 7.
> This is an example of the entity.

> I try different ways of subscriptions that all of them are accepted by orion like this:
> {
>   "description": "Notificar cambios en Aparcamientos",
>   "subject": {
>     "entities": [
>       {
>         "idPattern": ".*",
>         "type":"ParkingGroup"
>       }
>     ],
>      "condition": {
>       "attrs": [
>         "availableSpotNumber"
>       ]
>     }
>   },
>   "notification": {
>     "attrs" : ["availableSpotNumber"],
>     "http": {
>       "url": "https://webhook.site/925f3290-07af-4dc9-88d2-27bcba693be5"
>     }
>   }
> }
> When I update the data with this through postman in mode PUT:
> http://{{orion}}/v2/entities/urn:ngsi-ld:ParkingGroup:Cervantes/attrs/availableSpotNumber/value
> and Body (text/plain)  with value 2
> The data is well ubdate when I make in postman in mode GET:
> http://{{orion}}/v2/entities/urn:ngsi-ld:ParkingGroup:Cervantes/attrs/availableSpotNumber
> It returns:
> {
>     "type": "Property",
>     "value": 2,
>     "metadata": {}
> }
> But url of the subscription never receives anything
> what is wrong?
> How can I solve it? How could I debug Orion to understand why it doesn't update the subscriptors?
> The idea is to subscribe later cygnus.  I have read that I must add the attrsFormat for it in this way:
> "notification": {
>     "http": {
>       "url": "https://webhook.site/925f3290-07af-4dc9-88d2-27bcba693be5"
>     },
>     "attrs" : ["availableSpotNumber"],
>     "attrsFormat": "legacy"
>   }
> Thanks in advance
