terraform destroy fails with module outputs

[oliviabarrick]

I am using the following terraform module called test/test.tf:

provider "digitalocean" {
  token = "...."
}

resource "digitalocean_floating_ip" "kubernetes_ip" {
  region = "tor1"
}

data "external" "kubeconfig" {
  program = ["bash", "-c", "jq -Mc '{kubeconfig:\"\"}'"]

  query = {
    api_server = "${digitalocean_floating_ip.kubernetes_ip.ip_address}"
  }

  depends_on = ["digitalocean_floating_ip.kubernetes_ip"]
}

output "kubeconfig" {
  value = "${data.external.kubeconfig.result["kubeconfig"]}"
}

And then I have test.tf:

module "kubernetes" {
  source = "./test"
}

output "kubeconfig" {
  sensitive = true
  value = "${module.kubernetes.kubeconfig}"
}

Run:

terraform init
terraform apply

It will fail on terraform destroy:

➜  ttest git:(master) ✗ terraform destroy
digitalocean_floating_ip.kubernetes_ip: Refreshing state... (ID: 174.138.114.123)

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  - destroy

Terraform will perform the following actions:

  - module.kubernetes.digitalocean_floating_ip.kubernetes_ip


Plan: 0 to add, 0 to change, 1 to destroy.

Do you really want to destroy?
  Terraform will destroy all your managed infrastructure, as shown above.
  There is no undo. Only 'yes' will be accepted to confirm.

  Enter a value: yes

module.kubernetes.digitalocean_floating_ip.kubernetes_ip: Destroying... (ID: 174.138.114.123)
module.kubernetes.digitalocean_floating_ip.kubernetes_ip: Destruction complete after 0s

Error: Error applying plan:

1 error(s) occurred:

* module.kubernetes.output.kubeconfig: Resource 'data.external.kubeconfig' does not have attribute 'result' for variable 'data.external.kubeconfig.result'

Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.
