I just wanted to add a new yang module in yang data module.
The new yang module is the file _3gpp-nr-nrm-operatordu.yang.
But when I run the shell to install this module, it occurred this error:
Augment target node "/me3gpp:ManagedElement/gnbdu3gpp:GNBDUFunction" from module "_3gpp-nr-nrm-operatordu" was not found

The command I run is:
sysrepoctl -s /home/config/sysrepo/yang/:/tmp/etc/yang_model/ -p 600 -v3 -i /etc/yang_model/3_3gpp/_3gpp-nr-nrm-operatordu.yang

The shell file is :
install_yang_modules.txt

I have just added the command before
echo "Install Modules Successfully!"

the error:

The version of GNBDUFunction is rel16
