Some incomprehensible behavior when using a --defop=replace (netopeer2 version = 2.1.49)

[eekhdv]

Some incomprehensible behavior when using a --defop=replace with xml below:

<user-plane-configuration xmlns="urn:o-ran:uplane-conf:1.0" xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0">
        <static-srs-configurations nc:operation="delete"/>
</user-plane-configuration>

On netopeer-server side:

On netopeer2-cli side:

> edit-config --target=running --config=/root/test/test.xml --defop=replace
nc ERROR: SSH channel poll error (Socket error: disconnected).

While with --defop=merge it works as expected.
