Fiware Context Broker with entities geolocated

Question

I have a problem in retrieving entities using georeferenced queries. Use the v2 syntax.

This is my query:

GET /v2/entities?georel=near;maxDistance:1000&geometry=point&coords=13.52,43.61

and this is my entity:

{
    "id": "p1",
    "type": "pm",
    "address": {
        "type": "Text",
        "value": "Via Roma "
    },
    "allowedVehicleType": {
        "type": "Text",
        "value": "car"
    },
    "category": {
        "type": "Text",
        "value": "onstreet"
    },
    "location": {
        "type": "geo:json",
        "value": {
            "type": "Point",
            "coordinates": [ 13.5094, 43.6246 ]
        }
    },
    "name": {
        "type": "Text",
        "value": "p1"
    },
    "totalSpotNumber": {
        "type": "Number",
        "value": 32
    }
}

What is wrong? I followed the official documentation but I can not get any results as well. I also tried to reverse the coordinates, but the result does not change. Any suggestion is welcome.

Note that longitude comes before latitude in GeoJSON coordinates, while the coords parameters does in the opposite way.

Thus, assuming that your entity is located in Ancona city, I think that using "coordinates": [ 43.6246, 13.5094 ] will solve the problem.
