I am unable to reproduce your error.

tutorials.Custom-IoT-Agent % curl -iX POST \
  'http://localhost:4041/iot/devices' \
  -H 'Content-Type: application/json' \
  -H 'fiware-service: openiot' \
  -H 'fiware-servicepath: /' \
  -d '{
 "devices": [
   {
     "device_id":   "motion001",
     "entity_name": "urn:ngsi-ld:Motion:001",
     "entity_type": "Motion",
     "timezone":    "Europe/Berlin",
     "attributes": [
       { "object_id": "c", "name": "count", "type": "Integer" }
     ],

       { "name":"refStore", "type": "Relationship", "value": "urn:ngsi-ld:Store:001"}
     ]
   }
 ]
}'

I receive the following:

I assume that when you do so, you are receiving something different - could you post it.
