I am trying to mount netconf device as explained on the wiki:

https://wiki.opendaylight.org/view/OpenDaylight_Controller:Config:Examples:Netconf#Spawning_netconf_connectors_via_topology_configuration

feature:install odl-netconf-topology odl-restconf-all

then

PUT http://localhost:8181/restconf/config/network-topology:network-topology/topology/topology-netconf/node/vpp

<node xmlns="urn:TBD:params:xml:ns:yang:network-topology">
<node-id>vpp</node-id>
<host xmlns="urn:opendaylight:netconf-node-topology">127.0.0.1</host>
<port xmlns="urn:opendaylight:netconf-node-topology">2831</port>
<username xmlns="urn:opendaylight:netconf-node-topology">admin</username>

<tcp-only xmlns="urn:opendaylight:netconf-node-topology">false</tcp-only>
<keepalive-delay xmlns="urn:opendaylight:netconf-node-topology">0</keepalive-delay>
</node>

I got following exception:

Any idea what I am doing wrong?

More detailed log attached. I tried karaf-0.7.0-20170807.063951-1585.zip and netconf/caraf from local build (033e972eaf0d009ed0c0f54a109b6046fae80c99)
