Thanks, this works for me

I needed to change
yq r -

into

yq -P

yq --version
yq (https://github.com/mikefarah/yq/) version 4.21.1

Thanks, this change worked for me.

I encounter the same issue. But in the first step there is no full-cluster-state in config map. crying...

I do not have full-cluster-state configmap in a working cluster, no idea also ? @litao3rd did you find another option?

@jrab66 You can run the command rke util get-state-file now to pull the state file from a working cluster.

nop...I rebuild the cluster
