When setting the image, please set the image for all nodes in the cluster. It happens to work this time because 1.33 is the latest. The error message is also misleading, as it would work with 1.31.6 if all nodes had that image. You just can't mix nodes running images more than one minor version apart. It chooses a kubeadm based on the latest node image.
