Invalid memory address runtime error when adding node to remote cluster

[briandlees]

I have been trying to add a control-plane server to an existing cluster on a different node. This resulted in the following runtime error; any suggestions on how to alleviate this would be welcome:

node001:~ # k3d node create -c "https://10.10.0.x:6443" --role server --token obfuscatedtoken k3d-aclcluster-server-1

I should have added that this is the status of the remote cluster:

NAME STATUS ROLES AGE VERSION
k3d-aclcluster-server-0 Ready control-plane,etcd,master 48m v1.30.3+k3s1

Getting the same error when trying to build out a distributed cluster.
