JSON leaf-list output single element leaf-list does not use array

[olofhagsand]

JSON output, such as in RESTCONF, does not properly output JSON for leafrefs for single element lists

Example YANG:

     leaf-list l1{
       type string;
     }

Expected output:
{"l1":[1]}

Actual output:
{"l1":1}
