Exception has occurred: RPCError

[amiruka06]

Hello all, Hope you're doing good.
I'm trying to netconf on my CSR1kv router which I have hosted on my ESXi server.

When I'm trying to debug this code:

from ncclient import manager
from devices import router1

netconf_filter = open("filter-ietf-interfaces.xml").read()

with manager.connect(host=router1["host"], port=router1["port"], username=router1["username"], password=router1["password"], hostkey_verify=False) as m:
    interface_netconf = m.get(netconf_filter)
    print('Getting running config')

I'm getting this error on response:

Exception has occurred: RPCError
{'type': 'protocol', 'tag': 'unknown-element', 'severity': 'error', 'info': '<?xml version="1.0" encoding="UTF-8"?><error-info xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0"><bad-element>filter</bad-element>\n</error-info>\n', 'path': '\n    /rpc/get\n  ', 'message': None}
  File "C:\Users\aukka\Desktop\DevNetOps\NetConf\ncclient-1.py", line 33, in <module>
    interface_netconf = m.get(netconf_filter)

Obviously it seems that there's an error with m.get function.
Is there anyone who can help how I can fix this issue?
Thanks,

❯ pip freeze | grep ncc

This code works

from ncclient import manager
from ncclient.operations import RPCError
