ydk.errors.YModelError: Could not create data node: openconfig-if-ip:ipv4 : Schema node not found.. Path: openconfig-if-ip:ipv4

During use of openconfg + ydk, exception prevents the code from an execution.

My use case here is to create an addressed loopback interface on CSR, IOS-XE 16.8.1 with openconfig + ydk. (if I remove IPv4 semantics, but keep subinterface piece, code executes fine).

Could you please advise if this is an version mismatch / misuse / bug? Thank you,

(ydk) root@debian:~/ydk# pip freeze | grep ydk
ydk==0.8.0
ydk-models-ietf==0.1.5.post2
ydk-models-openconfig==0.1.5

(same behaviour on latest profile)
