* Library Elements API GET by name returns array
Making a GET request to the Library Elements HTTP API `api/library-elements/name/:name` will return an **array** of Library Element objects, but the documentation says it will return a Library Element object.
Example cURL POST request:
`curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer XXXXXXXXXXX" -d @request.json "https://my.grafana.net/api/library-elements/"`
request.json
```json
{
"model": {},
"kind": 1,
"name": "testing description3",
"uid": "basic3",
"id": 12345,
"version": 2
}
```
Example cURL GET request:
`curl -X GET -H "Content-Type: application/json" -H "Authorization: Bearer XXXXXXXX" -d @request "https://my/api/library-elements/name/testing description3"`
Example response:
```json
{
"result": [
{
. . .
}
]
}
```
