Are you running a container?

Yes, I am using a container (Docker, Kubernetes...)

Image type

normal

Expected behaviour you didn't see

This is a result of #1421 -specifically the removal of the intial Entity.

When I create a Group

 {
     "apikey":      "3020035",
     "cbroker":     "http://orion:1026",
     "entity_type": "Bell",
     "resource":    "/iot/d",
     "protocol":    "PDI-IoTA-UltraLight",
     "transport":   "HTTP",
 },

and provision an actuator:

{
      "device_id": "bell001",
      "entity_name": "Bell:001",
      "entity_type": "Bell",
      "endpoint": "http://iot-sensors:1041/iot/bell001",
      "commands": [ 
        {
          "name": "ring",
          "type": "command"
        }
      ],
      "static_attributes": [
          {"name": "refStore", "type": "Relationship","value": "urn:ngsi-ld:Store:001"}
      ]
    },

No Entity is created in the context broker.

Unexpected behaviour you saw

Sincent he initial insert of an Entity has been removed, so

curl -L 'http://localhost:1026/v2/entities/Bell:001?options=keyValues' \
-H 'fiware-service: openiot' \
-H 'fiware-servicepath: /'

is just returning:

{
    "id": "Bell:001",
    "type": "Bell",
    "ring": ""
}

However, I cannot PUT or PATCH an Entity with Orion

curl -L -X PUT 'http://localhost:1026/v2/entities/Bell:001/attrs/ring' \
-H 'fiware-service: openiot' \
-H 'fiware-servicepath: /' \
-H 'Content-Type: application/json' \
-d '{
      "type" : "command",
      "value" : ""
}'

is returning:

{
    "error": "NotFound",
    "description": "The requested entity has not been found. Check type and id"
}

Hmmm, the more I look into this, the more I think it is an Orion/NGSI-v2 bug. This issue is NGSI-v2 only since it isn't an issue for any NGSI-LD brokers.

Specifically, if I have a registration on Entity:XXX for attribute ZZZ, then a local instance shouldn't be necessary within Orion. It is really, really weird that Orion allows me to GET the device, but I can't actuate the device with a PUT/PATCH because "it doesn't exist" because it damn well does exist - I can see it with a GET. What doesn't exist at this point is local state data in Orion itself.

Orion should be updated to allow the forwarding of a patch on an attr if an attr is registered regardless of whether data is held within the CB. Then this issue disappears - Orion would work like any NGSI-LD broker already does.

IMHO this could be a bug for orion, but not an iotagent bug.
Your flow works fine when I include '?type=Belll'

curl -L -X PUT 'http://localhost:10026/v2/entities/Bell:001/attrs/ring?type=Bell' -H 'fiware-service: smartcity' -H 'fiware-servicepath: /' -H 'Content-Type: application/json' -d '{
      "type" : "command",
      "value" : "2"
}'

This issue should be transfer to orion repository.

[mapedraza]

This bug impacts both Orion and IoTAs. I just created an issue in the Orion repo: telefonicaid/fiware-orion#4430 describing the problem related with the CPrs and registrations.

[AlvaroVega]

If no PR or fix in iotas are expected this issue should be closed here.

[fgalan]

I understand that documentation improvements (to explain that an entity needs to be provisioned while telefonicaid/fiware-orion#4430 stills in order the commands mechanism to work) is part of #1465. In that case, I agree in closing this issue.
