RPC refuse banner commands on 16.12.08

When I try to configure login and motd banner on 16.12.08 version of IOS I get following error:

However same RPC call works perfectly fine on 17.06.04. Here is a RPC call created with python ydk:

<?xml version="1.0"?>
<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="26">
  <edit-config>
    <target>
      <candidate/>
    </target>
    <config>
      <native xmlns="http://cisco.com/ns/yang/Cisco-IOS-XE-native" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0">
        <hostname>MYXXX-ASW001</hostname>
        <banner>
          <login>
            <banner>******************************************************************************************
* WARNING: Unauthorized access to this system is forbidden and will be prosecuted by law.*
*   By accessing this system, you agree that your actions may be monitored and logged.   *
******************************************************************************************
</banner>
          </login>
          <motd>
            <banner>***********************************************
*         Do not forget forget to:            *
* -Document and save your changes             *
* -Turn your debugs off                       *
* -Possible loss of connection? reload in [m] *
***********************************************
</banner>
          </motd>
        </banner>
</native>
</config>
</edit-config>
</rpc>

What software did you use to send the RPC? If it is YDK, could you please share your Python script here?

It seems that your router did not like implicit end-of-line. I would suggest instead explicitly use char '\n' where you want to have the end-of-line and put the whole text into one line. Example of such banner configuration you can find here.

Yes, I am using YDK and I explicitly did \n. I am passing vars from dictionary like this:

      "banner": " ******************************************************************************************\n* WARNING: Unauthorized access to this system is forbidden and will be prosecuted by law.*\n*   By accessing this system, you agree that your actions may be monitored and logged.   *\n******************************************************************************************\n",
      "motd": " ***********************************************\n*         Do not forget forget to:            *\n* -Document and save your changes             *\n* -Turn your debugs off                       *\n* -Possible loss of connection? reload in [m] *\n***********************************************\n"

and then:

native_config = Cisco_IOS_XE_native.Native()
if 'banner' in kwargs:
    banner = kwargs.get('banner')
    native_config.banner.login.banner = dedent(banner)

if 'motd' in kwargs:
    motd = kwargs.get('motd')
    native_config.banner.motd.banner = dedent(motd)

Strange part is that this works fine on 17.06.04 version of IOS but not on 16.12.08
