Expected Behavior

Data tag should be correctly recognized

Current Behavior

"ydk - ERROR - Cannot find 'data' tag in RPC reply from device".

Steps to Reproduce

Query Arista switch with EOS 4.24.1.1F (tested with cEOS-lab-4.24.1.1F) for interface config

Your Script

from ydk.services import NetconfService, Datastore
from ydk.providers import NetconfServiceProvider
from ydk.models.openconfig import openconfig_interfaces as oc_interfaces
import logging

def set_logger():
logger = logging.getLogger("ydk")
logger.setLevel(logging.INFO)
handler = logging.StreamHandler()
formatter = logging.Formatter(("%(asctime)s - %(name)s - "
"%(levelname)s - %(message)s"))
handler.setFormatter(formatter)
logger.addHandler(handler)

set_logger()
provider = NetconfServiceProvider(address="172.18.0.3",
port=830,
username="admin",
password="abc123",
protocol="ssh")

netconf = NetconfService()
interfaces = oc_interfaces.Interfaces()
interface = interfaces.Interface()
interface.name = 'Ethernet2'
interfaces.interface.append(interface)
cfg = netconf.get_config(provider, Datastore.running, interfaces)
