I think a better approach is to use the label that should uniquely identify doks-debug.
Personally, I generally prefer using custom columns over dealing with JSON whenever I can, so this is how I'd go about it:
POD_NAME=$(kubectl get pod -l name=doks-debug --field-selector spec.nodeName=${NODE_NAME} --no-headers -o custom-columns=:.metadata.name)

@dhij could you check in on that? Take care to add -n kube-system still if you use Timo's command.

-ojsonpath='{.items[0].metadata.name}'gave me a pod name for cilium so I was thinking we could use this approach or sort by.metadata.creationTimestampbefore choosingitems[0]
