YCodeError Cisco_IOS_XR_ipv4_bgp_oper module on ydk-py 0.8.3

[arynair]

Issue tracker is ONLY used for reporting bugs. Please use the YDK Community for any support issues.

Expected Behavior

The YDK should be able to read all BGP data (top level container) without breaking.

Current Behavior

The script breaks after read with YcodeError

Steps to Reproduce

using docker command for environment ( as per documentation for ydk-pyt 0.8.3) docker run -it ydkdev/ydk-py

ydk 0.8.3 ydk-models-cisco-ios-xe 16.9.3 ydk-models-cisco-ios-xr 6.6.2 ydk-models-cisco-nx-os 9.2.3 ydk-models-ietf 0.1.5.post2 ydk-models-openconfig 0.1.6.post1 ydk-service-gnmi 0.4.0.post1

Your Script

from ydk.providers import NetconfServiceProvider
from ydk.services import CRUDService
import logging
from ydk.models.cisco_ios_xr import Cisco_IOS_XR_ipv4_bgp_oper as xr_ipv4_bgp_oper

#logging
log = logging.getLogger('ydk')
log.setLevel(logging.INFO)
handler = logging.StreamHandler()
log.addHandler(handler)

def bgp_oper_main(device_netconf
        bgp_oper_obj = xr_ipv4_bgp_oper.Bgp()
        bgp_oper_instance_list_obj = xr_ipv4_bgp_oper.Bgp.Instances.Instance()
        bgp_oper_instance_list_obj.instance_name = 'default'
        bgp_oper_obj.instances.instance.append(bgp_oper_instance_list_obj)
        crud_service.read(device_netconf,bgp_oper_obj)

if __name__ == "__main__":


    #creating a CRUD(Create Read, Update , Delete) instance over Netconf. Refer ydk-py documentation for details.    
    crud_service = CRUDService()
    device_netconf=NetconfServiceProvider(address=ssh_ip,
                                                    port=port,
                                                    username=username,
                                                    password=password,
