topoprocessing CSIT jobs failing (NPE when doing "Insert Underlay Topologies")

the topoprocessing CSIT jobs are failing in their suite setups when running
the "Insert Underlay Topologies" step. This job:

https://jenkins.opendaylight.org/releng/view/CSIT-Jobs/job/topoprocessing-csit-1node-topology-operations-only-beryllium/

the karaf.log is kept as an artifact in the job for reference. A few more
details below, but you can also see most of them in the robot logs.

The PUT is sent to:

/restconf/config/network-topology:network-topology/topology/network-topo:1

The data in the PUT is:

<topology xmlns="urn:TBD:params:xml:ns:yang:network-topology" xmlns:pcep="urn:opendaylight:params:xml:ns:yang:topology:pcep"> <topology-id>network-topo:1</topology-id> <topology-types> <pcep:topology-pcep></pcep:topology-pcep> </topology-types> <node> <node-id>pcep:1</node-id> <pcep:path-computation-client> <pcep:ip-address>192.168.1.1</pcep:ip-address> </pcep:path-computation-client> </node> <node> <node-id>pcep:2</node-id> <pcep:path-computation-client> <pcep:ip-address>192.168.1.2</pcep:ip-address> </pcep:path-computation-client> </node> <node> <node-id>pcep:3</node-id> <pcep:path-computation-client> <pcep:ip-address>192.168.2.1</pcep:ip-address> </pcep:path-computation-client> </node> <node> <node-id>pcep:4</node-id> <pcep:path-computation-client> <pcep:ip-address>192.168.2.2</pcep:ip-address> </pcep:path-computation-client> </node> <node> <node-id>pcep:5</node-id> <pcep:path-computation-client> <pcep:ip-address>192.168.2.3</pcep:ip-address> </pcep:path-computation-client> </node> </topology>

The response code is 500, and the response content is:
