Actual Behavior

The error message below

Error: Provider produced inconsistent result after apply
When applying changes to kubernetes_manifest.secret_example_cluster_config, provider
"provider["registry.terraform.io/hashicorp/kubernetes-alpha"]" produced an unexpected new value: .object.stringData:
was cty.MapVal(map[string]cty.Value{"foo":cty.StringVal("bar")}), but now null.
This is a bug in the provider, which should be reported in the provider's own issue tracker.
