I received this error on this particular GHA run https://github.com/getsentry/ops/actions/runs/9392078538/attempts/1#summary-25865602233

The worfklow run was successful and the plan looks good regardless of the error?

Planning failed. Terraform encountered an error while generating this plan.

Locally:

Terraform planned the following actions, but then encountered a problem:

  # google_compute_disk.data[1] will be updated in-place
  ~ resource "google_compute_disk" "data" {
        id                        = "projects/mattrobenolt-kube/zones/us-west1-b/disks/zookeeper-test-2-data"
