Erroneous error from /api/1.3/coordinates when updating a coordinate

[ocket8888]

$ curl -skb lab-cookie.jar -X PUT -d '{"id": 10, "name": "testquest", "latitude": -90, "longitude": 180}' "https://<lab machine>:6443/api/1.4/coordinates" | jq .
{
	"alerts": [
		{
			"text": "missing key: id",
			"level": "error"
		}
	]
}
 $ curl -skb lab-cookie.jar "https://<lab machine>:6443/api/1.4/coordinates?name=testquest" | jq .                                                  
{
	"response": [
		{
			"id": 10,
			"name": "testquest",
			"latitude": 0,
			"longitude": 0,
			"lastUpdated": "2018-10-25 16:40:33+00"
		}
	]
}

same data works fine when submitting a POST to create a coordinate pair, but for some reason PUT is unable to find the "id" key.

actually, this comes down to the docs. They say you can specify the ID field in the request body, but really it's a required query parameter and has no effect in the request body.
