Unable to get the complete running config using netconf-yang

[kn2022]

I have a cisco Cisco IOS XE Software, Version 17.03.05 on cisco ASR1001-HX (1SR) processor
I am running this simple netconf yang code to get the runninmg config

import xmltodict
import xml.dom.minidom
from ncclient import manager

router = {
'ip': '192.1168.100.221',
'port': '830',
'username': 'admin',
'password': 'XXXXXXXXXXXX'
}

m = manager.connect(host=router['ip'], port=router['port'], username=router['username'],
password=router['password'],device_params={'name':'iosxe'} ,hostkey_verify=False)

running_config = m.get_config("running").xml
print(xml.dom.minidom.parseString(running_config).toprettyxml())
m.close_session()

I get the running configuration. But I do not get any interface information, or any sub interface information including port channel in this. 
Any suggestions.

Would appear the issue you're facing is likely due to the way you're retrieving the running configuration. By default, get_config("running") on Cisco IOS XE with Netconf might not include detailed interface information like subinterfaces or port channels. Try updating your filter.

filter = """
<filter>
  <include xmlns="urn:ietf:params:xml:ns:yang:Cisco-IOS-XE-cfg">
    <interfaces/>
  </include>
</filter>
"""

running_config = m.get_config("running", filter=filter).xml
print(xml.dom.minidom.parseString(running_config).toprettyxml())

strange, but this code was working earlier.
According to the netconf-yang protocol it should have returned the complete configuration. Anyways I tried your suggestions and still not getting anything.

import xmltodict
import xml.dom.minidom
from ncclient import manager

router = {
'ip': '192.1168.100.221',
'port': '830',
'username': 'admin',
'password': 'XXXXXXXXXXXX'
}

netconf_filter = """
<filter>
<include xmlns="urn:ietf:params:xml:ns:yang:Cisco-IOS-XE-cfg">
<interfaces/>
</include>
</filter>
"""

m = manager.connect(host=router['ip'], port=router['port'], username=router['username'],
password=router['password'],device_params={'name':'iosxe'} ,hostkey_verify=False)

running_config = m.get(filter=netconf_filter).xml
print(xml.dom.minidom.parseString(running_config).toprettyxml())
m.close_session()


gives me:
$ python3 newfile2.py
Traceback (most recent call last):

Try it uses the itef model though 

from ncclient import manager
import os
import json

# Set up device info
username=os.environ["CSR1_USER"]
password=os.environ["CSR1_PASSWORD"]
port=os.environ["CSR1_PORT_NETCONF"]
host=os.environ["CSR1_HOST"]
device_params={"name":"iosxe"}

netconf_filter = """ <filter xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"> <interfaces xmlns="urn:ietf:params:xml:ns:yang:ietf-interfaces"></interfaces> </filter> """

with manager.connect(host=host, port=port, username=username, password=password, hostkey_verify=False, device_params=device_params) as m:
c = m.get_config('running', netconf_filter).data_xml
with open("%s_int.xml" % host, 'w') as f:
f.write(c)
