Hi all,
I am working on Boron release and am trying to call user difined RPC in netconf
device using odl Restconf.
The URI being used is
http://localhost:8181/restconf/operations/network-topology:network-topology/topology/topology-netconf/node/my/yang-ext:mount/myos-op:ping
Method :POST
Body :
{
"input" :
{
"myos-op:host" : "192.168.128.96",
"myos-op:count":"5"
}
}
The request fails with following error response :
{
"errors":{
"error":[
{
"error-type":"application",
"error-tag":"operation-failed",
"error-message":"The operation encountered an
unexpected error while executing.",
"error-info":"java.lang.IllegalStateException: Unknown
child(ren) node(s) detected, identified by:
(urn:ietf:params:xml:ns:netconf:base:1.0)ok, in: RPC Output output\n\tat

I checked the device debug level log and find the RPC was executed succeefully,
but failed to return the response.
netopeer-server log:
netopeer-server[5852]: SSH log: ssh_socket_pollcallback: Received POLLOUT in

But it is very strange, I can use the netopeer-cli to call the RPC and get the
right response.
this is my netconf device YANG model define:
module myos-op {
yang-version 1;
namespace
"urn:my.com:mgmt:myos-op";
prefix "op";
organization
"my Working Group";
description
"This module contains a collection of YANG definitions for
ping function.
This version of this YANG module is part of RFC 7223; see
the RFC itself for full legal notices.";
revision "2017-01-09" {
description "Initial revision.";
reference
"RFC 7223: A YANG Data Model for myOS";
}
container system {
description
"System group configuration.";
leaf hostname {
type string;
description
"The name of the host. This name can be a single domain
label or the fully qualified domain name of the host.";
}
} // container system
rpc ping {
description
"Ping destination host.";
input {
leaf host {
type string;
description
"Destination host.";
}
leaf count {
type uint32;
description
"ping count.";
default "3";
}
}
output {
leaf result {
type string;
}
}
} // rpc ping
} // myos-op
Kindly help me how to fixed this issue. Thank in advance._______________________________________________
