Posting to orion gets me to "Attribute must be a JSON object" - fiware-orion

Question

I am sending this to Orion:
curl --location --request POST 'http://xx.xx.xx.xx:1026/ngsi-ld/v1/entities/' \
--header 'link: <https://smartdatamodels.org/context.jsonld>; rel="http://www.w3.org/ns/json-ld#context"; type="application/ld+json"' \
--header 'Content-Type: application/json' \
--data-raw '{
"id": "urn:ngsi-ld:Device:01",
"type": "Device",
"description": "L9A",
"category": {
"value": ["sensor"]
},
"serialNumber": {
"value": "38479144"
},
"controlledProperty": {
"value": ["Water Supply"]
},
"owner": {
"value": ["Me"]
},
"location": {
"type": "Point",
"coordinates": [20.200416, 30.261837]
}
}'
and I get this:
Error 400: Bad Request
{
"type": "https://uri.etsi.org/ngsi-ld/errors/BadRequestData",
"title": "Attribute must be a JSON object",
"detail": "description"
}
I validated by json object and it passes. What am I doing wrong?

Answer 1

Look a little closer at your error message, especially:
detail": "description"
That's the name of the attribute that is not a JSON object:
"description": "L9A"
If you change it to:
"description": {
"type": "Property",
"value": "L9A"
}
that part should be OK.
But, the type member seems to be missing for all your attributes.
you'll need to add "type": "Property" to all of them, except "location" that's a GeoProperty:
"location": {
"type": "GeoProperty",
"value": {
"type": "Point",
"coordinates": [20.200416, 30.261837]
}
}
Perhaps spend some time reading the NGSI-LD specification?
