Terraform panic: value is null

[AndreaGiardini]

Hello everyone 👋

I am having trouble using this provider since version 2.5.0. ATM I am stuck on version 2.4.1 since every version after that crashes terraform for me. I have attached the panic log below. Let me know in case you need any other info

Terraform Version, Provider Version and Kubernetes Version

Terraform version: 1.1.2 (terraform cloud)
Kubernetes provider version: every version since 2.5.0.
-> 2.4.1 is the last known working version
Kubernetes version: 1.20.10

Panic Output

Steps to Reproduce

1. terraform plan

[AndreaGiardini]

The panic is related to this resource:

resource "kubernetes_manifest" "letsencrypt_crd" {

  depends_on = [helm_release.cert_manager]

  lifecycle {
    ignore_changes = all
  }

  manifest = {
    "apiVersion" = "cert-manager.io/v1"
    "kind"       = "ClusterIssuer"
    "metadata" = {
      "name" = "letsencrypt"
    }
    "spec" = {
      "acme" = {
        "email"          = "[email protected]"
        "privateKeySecretRef" = {
          "name" = "letsencrypt"
        }
        "server" = "https://acme-v02.api.letsencrypt.org/directory"
        "solvers" = [
          {
            "http01" = {
              "ingress" = {
                "class" = "ingress-nginx"
              }
            }
          },
        ]
      }
    }
  }
}

When this resource is removed terraform does not crash

[AndreaGiardini]

In case you find yourself in the same situation, the following workaround works for me:

• Remove the resource from your manifest -> terraform apply
• Upgrade provider -> terraform apply
• Restore the resource -> terraform apply
