get_config with filter nc: namespace issue

Hello, I am using ansible to configure my system over ansible. I am making a get_config query with a filter.

the filter is : config_filter:

I call the netconf connection module’s get_config with the above filter.

At the device I am receiving the following RPC :
<nc:rpc message-id=“urn:uuid:6a853fc2-c3a0-4a74-a579-78020ae28270” xmlns:nc=“urn:ietf:params:xml:ns:netconf:base:1.0”>
nc:get-config
nc:source
nc:running/
</nc:source>









</nc:get-config>
</nc:rpc>

I am unable to find at which point exactly are the wrapping tags added. Also , since namespace (nc:) is not added to the filter tag, the RPC is failing at the device.
