Above is normal, not an error condition. Both True or False are normal conditions.

Expected behaviour

Nodes with condition EtcdIsVoter should not be reported as an error. This is normal and expected condition for K3s control-plane nodes.

It appears k8sgpt is making assumptions about node status conditions it might not be expecting. Ideally it can be made aware of this as a normal condition, at worst perhaps unexpected conditions should be presented as a warning not an error?

Actual behaviour

Nodes with condition EtcdIsVoter is reported as an error.

Additional Information

EtcdIsVoter can be either True or False, neither condition is to be considered an error condition. It is simply a status if the node is an etcd voting member or a learning member.
