Hi,
the problem is that libnetconf2 failed to load ietf-yang-library. The strange thing is that the module is loaded internally, so it should always be there. Probably you trying to explicitly load it in another revision caused some trouble, I will try to look into it, but you do not need to do that at all. Still, that will likely not solve your problems because I think you are not using the most recent libyang version, so please update it.

Regards,
Michal

Hello,
After resolving a couple of issues on my end and using the latest libyang and libnetconf2 libraries, this issue was resolved.

Thank you so much for your help and feel free to close this issue.
