get device API using uniqueId does not work

I tried to retrieve a device info using uniqueId appended on the url, but it does not work. it always returns me the entire data instead of the specific one. Here is the url I use: curl -X GET "http://172.x.x.x:xxxx/api/devices?uniqueId=123456" -H "Authorization: Basic abdksaxxxxxxxxxxxxxxxxxxxxxxx"

Any one can help?

Option to use uniqueId was added after 3.13, so you will be able to use it in the next release only.
