Autoprovison only works with the defined defaultResource

[fbuedding]

IoT Agent Node Lib version the issue has been seen with

3.3.0

Bound or port used (API interaction)

Other

NGSI version

NGSIv2

Are you running a container?

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

Image type

normal

Expected behaviour you didn't see

When a Service Group is provisioned with an api-key, resource other than the defaultResource and autoprovision is set to true documented here, then no device will be autoprovsioned upon receiving measurements. In my understanding the documentation let it sound like it should autoprovision a Device with the corresponding resource.

Bonus: when posting via http it also uses the default entity_type and not the one defined in the service group

Unexpected behaviour you saw

It did not autoprovision a device, it said it could not find one

Steps to reproduce the problem

# Create Service Group
curl --location 'http://localhost:4061/iot/services' \
--header 'fiware-service: openiot' \
--header 'fiware-servicepath: /' \
--header 'Content-Type: application/json' \
--data '{
 "services": [
   {
     "apikey":      "8b661f3b-6335-40d4-86ee-4d9119fe26e5",
     "cbroker":     "http://orion:1026",
     "entity_type": "House",
     "resource":    "/iot/house",
     "autoprovision":"true"
   }
 ]
}'

Hi @fbuedding, @fgalan
I would like to contribute on this issue.

Great to hear this @vivekNEC. I can assign you this issue. @fbuedding documented pretty well this issue, but, if you have any further question, feel free to post here.

Consider to check:

• If you get errors when using a resource different than the default (this means, defining a resource when creating the service group (POST /iot/services) with a value that differs from the default resource) both for autoprovisioned devices (the error shown in this issue) and also for previously provisioned device (devices created in advance)
• The behaviour for both IoT Agents: IoT Agent JSON (default resource: /iot/json) and IoT Agent Ultralight (default resource: /iot/d).
• Test if it works both for HTTP and MQTT transport protocol (for each IoT Agent)

When this issue gets addressed, have a look to doc/api.md file, look for FIXME mark and remove the 2 ones regarding #1524 (introduced in PR #1551)
