Orion CB saves device with 'entity_name' value in 'id' field

Question

I'm trying to develop IoTA with lazy attributes. And found that Context Broker saves device 'entity_name' field in 'id', so when CB makes request for lazy attributes, IoTA can't found device with such id.

With purpose to create device entity I make this request to IoTA:

'devices': [{
    'device_id': 'idSensor14',
    'entity_name': 'nameSensor14',
    'entity_type': 'anysensor',
    'attributes': [
        {
            'name': 't',
            'type': 'celsius'
        }
    ],
    'lazy': [
        {
            'name': 'b',
            'type': 'mybits'
        }
    ]                 
}]

Then if we request entitites list in CB ('v2/entities/') we discover:

{ "id":"nameSensor15",
    "type":"anysensor",
    "t":{"type":"celsius","value":"","metadata":{}}}

It seems that CB saves device with wrong id. This is request for lazy attributes:

data = {
    "entities": [{
        "isPattern": "false",
        "id": myid,
        "type": entity_type
    },
    "attributes": ["b"]
]}

And this is error in IoA log:

op=IoTAgentNGSI.ContextServer | srv=myhome | subsrv=/sensors | msg=Query error [DEVICE_NOT_FOUND] handling request: No device was found with id:nameSensor15

If delete entity_name from registration request, then CB will use device id = 'anysensors:idSensor14'. My Orion version is 1.7.0, and iotagent-node-lib version is 2.5.1.

Answer 1

The reason was in using upper case letters in fiware service name for device registration headers and iota config, so I should use myhome instead of myHome, for example. It's same for memory and mongo device registry types.
