Terraform-provider-kubernetes: Unable to show resources with self_link in metadata

[joe-a-t]

Terraform Version, Provider Version and Kubernetes Version

Terraform version: v0.15.3
Kubernetes provider version: v2.3.1

Affected Resource(s)

kubernetes_config_map

kubernetes_namespace

Almost certainly others as well

Terraform Configuration Files

resource "kubernetes_config_map" "example" {
  metadata {
    name = "my-config"
  }
}

Debug Output

Panic Output

Steps to Reproduce

Create a kubernetes_config_map with v2.3.0 (or earlier) of the Kubernetes provider

Run terraform state show kubernetes_config_map.example to verify it works

Upgrade the Kubernetes provider to v2.3.1

terraform state show kubernetes_config_map.example will no longer work with unsupported attribute "self_link" error message

Expected Behavior

The resource should have been output.

Actual Behavior

unsupported attribute "self_link" error message

Important Factoids

This also causes errors if you try to open terraform console in any affected directories.

Looks like we need a StateUpgrader to delete the self_link attribute from state for it to work with the terraform state command. I was able to reproduce and this doesn't seem to be affecting plan or apply.

A workaround here is run terraform refresh which will fix the state.
