spec.ephemeralContainers[0].targetContainerName: Not found

Getting this error attaching to a node-based pod

spec.ephemeralContainers[0].targetContainerName: Not found

What can I do to debug this further?

a lot of the kubectl debug examples seem to cover the case where the pod name and container name are the same which can be confusing. But the --target is actually the containerName (and you likely used the pod name instead - the error is simply saying the container itself cannot be found in the specified pod). kubectl get pods POD -ojsonpath='{.spec.containers[*].name}' should show the names of the containers in the pods.
