Run-time notification failure

Core Engine and APIs

Hi

In our use case, we need to send run-time notification to ConfD.
I use confd_register_notification_stream to register stream my-rt-ntf to ConfD, and use confd_notification_send to send notification to ConfD. But I can’t receive the notification in client (which subscribes to this stream).
I set debug level to CONFD_PROTO_TRACE, the following debug information is printed out by ConfD. There is ‘undefined’ in the debug information. I tried to use the default stream NETCONF, it has the same issue.
What does ‘undefined’ in debug information mean? How should I resolve this issue? Thanks a lot.

14-Mar-2017::07:18:56.560 6971/7f3b04ff9700/13 SEND op=15 isrel=0 th=-1 {170,‘my-rt-ntf’,undefined,{19,{2017,3,14,7,18,56,560913,0,0}},0,{hxml,[{[1945824463|1621884104],start},{1909855274,{12,1}},{[1945824463|1724773219],start},{1646628167,{12,2112}},{[1945824463|1724773219],stop},{[1945824463|1724773219],start},{1646628167,{12,32}},{[1945824463|1724773219],stop},{[1945824463|1621884104],stop}]}}

Hi,

If you haven’t yet, you may want to compare your confd.conf settings and application setup to the examples.confd/netconf_notifications example.

Terminal window 1:

$ pwd
/Users/tailf/confd-6.3.1/examples.confd/netconf_notifications
$ make all start

Terminal window 2:

$ netconf-console --create-subscription=interface

Terminal window 1 typing 'u':

u

Terminal window 2:
