REST API for openconfig-system - handler not implemented

[Rajavelu balaji]

Hi,

Greetings of the day!

The REST API for openconfig-system seems not implemented. Any REST query for openconfig-system fails with the below error.

QUERY:

=======

curl -X GET "https://<IP-address>/restconf/data/openconfig-system:system" -H "accept: application/yang-data+json"

ERROR:

=======

{
  "ietf-restconf:errors": {
    "error": [
      {
        "error-type": "application",
        "error-tag": "operation-failed"
      }
    ]
  }
}

The /var/log/syslog says 'Not implemented'. 

SYSLOG:

Please point me to a fix or solution. Or if there is a team already working on the module, then I would like to join the team and contribute to the community. 

I made sure that my build and setup works by querying the REST API queries in openconfig-interfaces, and they worked fine. The issue is with APIs in openconfig-system.

Thanks,
