Crazyswarm crashes throwing an instance of 'XmlRpc::XmlRpcException'

[DARCLab]

I am trying to connect/fly one Crazyflie using hover_swarm.launch with OptiTrack motion capture system. I can successfully communicate with the CF.

crazyswarm server crashes with the following error message:
crazyflieTerminalOutput.txt

Here is my hover_swarm launch file
hover_swarm.txt

The main motive parameters are:
Broadcast Frame: On
Local interface: 192.168.1.3
Labeled Markers: On
Unlabeled Markers: Off
Asset Markers: Off
Rigid Bodies: On
Command Port: 1510
Data Port: 1511
Multicast interface: 239.255.42.99

mocap_helper.launch works publishing out the points and rigid body of my CF:
frame 110:

And have also ran the NatNetSDKCrossplatform and got the following result:

This crash usually means that there is an issue with your crazyflies.yaml file (or crazyflieTypes.yaml, in case you edited that one). Could you share those files?
