Thanks for reporting this. I can reproduce the issue and it looks like it's indeed a problem in the provider.

Note to fixer: it looks like we can't really use the polymorphic status viewers from kubectl for StatefulSets that are not using RollingUpdate strategy. Error comes from here: https://github.com/hashicorp/terraform-provider-kubernetes/blob/cbe392a099bf3a6f7e9981e58cb53be0cdee97c6/vendor/k8s.io/kubectl/pkg/polymorphichelpers/rollout_status.go#L128

You can temporarily work around this issue by setting wait_for_rollout = false on the affected resource. For example:

resource "kubernetes_stateful_set" "test" {
  metadata {
    name = "test-1166"
  }
  wait_for_rollout = false
  spec {
...
