Data is invalid according to the yang model.

IBMeR
Level 1
Level 1

I'm tring to create IPIP or GRE tunnel:
tunnel=native.interface.Tunnel()
tunnel.name=999
tunnel.description="test123"
tunnel.vrf.forwarding="Stateful"
tunnel.ip.address.primary.address="192.168.206.206"
tunnel.ip.address.primary.mask="255.255.255.252"
tunnel.ip.tcp.adjust_mss=1360
tunnel.tunnel.source="Loopback0"
destination=tunnel.Tunnel_.Destination()
destination.ipaddress_or_host="8.8.8.8"

tunnel.tunnel.destination=destination
tunnel.tunnel.mode.ipip=tunnel.tunnel.mode.Ipip()
native.interface.tunnel.append(tunnel)
crud.create(provider,tunnel)

 

And receive error like it:

2019-01-09 19:49:28,189 - ydk - INFO - Connected to x.x.x.x on port 830 using ssh with timeout of -1

Am I doing anything wrong or is it bug?

Hello IBMeR
I built a test based on your script, but could not reproduce the issue with YDK-0.8.0 and cisco-ios-xe 16.8.1 model bundle. I only can assume that model bundle that you are using and device are not fully compatible. I need more details of your environment to make the judgement.
FYI
My test script
from __future__ import absolute_import
import logging
from argparse import ArgumentParser
from ydk.providers import CodecServiceProvider
from ydk.services import CodecService

from ydk.models.cisco_ios_xe import Cisco_IOS_XE_native

def enable_logging(level):
log = logging.getLogger('ydk')
log.setLevel(level)
handler = logging.StreamHandler()
formatter = logging.Formatter(("%(asctime)s - %(name)s - %(levelname)s - %(message)s"))
handler.setFormatter(formatter)
log.addHandler(handler)

def build_tunnel(native):
tunnel=native.interface.Tunnel()
tunnel.name=999
tunnel.description="test123"
tunnel.vrf.forwarding="Stateful"
tunnel.ip.address.primary.address="192.168.206.206"
tunnel.ip.address.primary.mask="255.255.255.252"
tunnel.ip.tcp.adjust_mss=1360
tunnel.tunnel.source="Loopback0"

destination=tunnel.Tunnel_.Destination()
destination.ipaddress_or_host="8.8.8.8"
tunnel.tunnel.destination=destination

tunnel.tunnel.mode.ipip=tunnel.tunnel.mode.Ipip()
native.interface.tunnel.append(tunnel)

if __name__ == "__main__":
"""Execute main program."""
parser = ArgumentParser()
parser.add_argument("-v", "--verbose", help="print debugging messages", action="store_true")
args = parser.parse_args()

# log debug messages if verbose argument specified
if args.verbose:
enable_logging(logging.DEBUG)

# create codec provider and service
provider = CodecServiceProvider(type="xml")
codec = CodecService()

The run results
yan@ubuntu-yan:~/ydk-workspace/ydk-gen$ python ./scripts/tests/test_xe_tunnel.py
