Failed to create `rpc-reply`

[SaiCharanMarrivada]

When I tried to do lyd_new_any to create reply for an rpc, with name "data", I got this error:

libyang[0]: Any node "data" not found.

Then you have used wrong parameters. An RPC without data output node, most likely. If you add some details I may be able to tell you more.

[SaiCharanMarrivada]

The rpc is an action of this form,

<action xmlns="urn:ietf:params:xml:ns:yang:1">
  <dataPorts xmlns="astrome:gigamesh">
    <zero>
      <oam>
        <cfmTrace>
          <maintenanceDomainLevel>5</maintenanceDomainLevel>
          <macAddress>00:02:c9:51:a1:ec</macAddress>
          <vlan>20</vlan>
        </cfmTrace>
      </oam>
    </zero>
  </dataPorts>
</action>

The action definition should also have output with leaf data?

[michalvasko]

I do not know what you are trying to achieve but I see that you do not really understand what you are doing. All lyd_new_* functions create nodes that must be present in the corresponding YANG modules. For RPC/action output, you can only create nodes that are defined as substatements of output in the RPC/action.

[SaiCharanMarrivada]

Oh, so the output argument should be the one which is defined in the output of action.

[michalvasko]

Yes, that is exactly what I wrote.

[SaiCharanMarrivada]

If this is how an action is modelled,

        action cfmTrace {
            input{
                leaf maintenanceDomainLevel{
                    type uint8;
                    description "0-7";
                }
                leaf macAddress{
                    type string;
                    description "MAC address";
                }
                leaf vlan{
                    type uint32;
                    description "VLAN 1-4095, 0: disabled";
                }
            }
            output{
	           anyxml response {
                   description "response of cfmTrace";
               }
            } 
        }

Then, is this the correct reply from the server?

<rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="urn:uuid:dbd21671-cb98-498c-bb5a-baf760fe20c5">
  <response xmlns="astrome:gigamesh">ttl 1: LTM with id 390485514
        reply from 00:02:c9:51:a1:ec, id=390485514, ttl=0, RlyHit
</response>
</rpc-reply>

[michalvasko]

Yes, in NETCONF it is.
