[CX] meta() function does not support type field as n1ql but also does not throw any error

Query issued:
SELECT distinct name FROM default_shadow WHERE META(default_shadow).`type` = "json";

Result:
curl -s --data pretty=true --data-urlencode statement@file2.txt http://172.23.107.182:8095/analytics/service

"metrics":

{ "elapsedTime": "46.094561ms", "executionTime": "45.597679ms", "resultCount": "0", "resultSize": "0" }

}

This doesnt return any error for cbas.

n1ql meta function has following fields:
"$1":

{ "cas": 1475097795040575488, "flags": 4042322160, "id": "query-testemployee10153.1877827-0", "type": "json" }

while cbas meta function has:
"rev": 1,
"cas": 1475016704135397376,
"flags": -252645136,
"lock": 0,
"expiration": 0,
"id": "query-testemployee99397.2740161-0",
"seq": 1

If type is not being supported as meta, then it should return an error.
