Question:
Actives do it perfectly but can´t interact with Lazies and Commands from the Broker

Description:
As for what I think "not answered question " in Fiware IotAgent: can't send command to a device, I tried to implement the example in https://fiware-iotagent-lwm2m.readthedocs.io/en/latest/deviceProvisioning/index.html but, I am not being able to interact with both Lazy and Command attributes from the Broker. I tried with Orion V1 and V2 querying both from Postman and .sh files and the error code below remains.

{
"errorCode":

{ "code": "404", "reasonPhrase": "No context element found" }

}

The readings work just perfectly. Hence, I can see the updated active attributes values in Broker when running a series of SET > in the LwM2M client.js.

Both Fiware GEs (Agent and Broker) are running in the same VMWare Workstation/Fiware Instance.

Following I have the main configurations I am using and can share more details if needed. Any help will be more than welcome!

*1) docker-compose.yml *
