      Question:
      Querying lwm2m active attribute in Orion

      Description:
      I have the following configuration for an active lightweightm2m-iotagent attribute (a temperature sensor value). Fiware's IoT agent turns IPSO objects into lazy attributes but I add a mapping to make it an active attribute as in the documentation:

      types: {
      'Type': {
      service: 'service',
      subservice: '/service',
      commands: [],
      lazy: [],
      active: [

      { "name": "t", "type": "number" }

      ],
      lwm2mResourceMapping: {
      "t":

      { "objectType": 3303, "objectInstance": 0, "objectResource": 5700 }

      }
      },

      According to the documentation for the iotagent-node-lib:

      NGSI queries to the context broker will be resolved in the Broker database.

      However, when I query my active attribute in Orion, Orion also queries the lightweightm2m-iotagent, requesting a bogus /3303/0/0 path which doesn't even exist in the IPSO definition.

      curl -H "Fiware-service: service" -H "Fiware-servicepath: /service" http://172.17.0.1:1026/v2/entities/entity1:Type/attrs/t/value

      How can I set up the configuration to get the behavior stated in the documentation, resolving a query for an active attribute in the broker database and avoiding these bogus queries?
