Not able to create_node when it is augumented from another module i get runtime erro couldn't send payload

jarulsel@cisco.com — Mon, 08 Apr 2019 12:25:45 GMT

Here is code snippet on what i am trying

>>> from ydk.path import NetconfSession
>>> from ydk.path import Codec
>>> from ydk.types import EncodingFormat
>>> session = NetconfSession('10.64.86.95', 'lab', 'lab')

>>> root = session.get_root_schema()

>>> voice = root.create_datanode("Cisco-IOS-XE-native:native" , "")

>>> gw = voice.create_datanode("ios-voice:voice/vrf", "1") -----> ios-voice is prefix of another module which is augumented in native. The container voice and it leaf vrf are a grouping in module Cisco-IOS-XE-voice (prefix:ios-voice).
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
RuntimeError: YClientError: Could not send payload
whenever i want to create node of leafs or container which are augumented from another module it reports "RuntimeError: YClientError: Could not send payload"

while if i create node of leaf from the same module native , then it gets created .
>>> gw = voice.create_datanode("user-name/name", "test")

Is there anything i am need to take care to create nodes of leafs which are from another module.

I found the issue as it is checking for Module name and i was using module prefix . Once i changed ios-voice to module name which is 'Cisco-IOS-XE-voice:voice/vrf ' it is able to create the node.

Thanks for the pointer .
