Expected output

I was expecting the plan not to fail.

Actual output

After creating the TURN app any plan will fail.

╷
│ Error: failed to make http request
│ 
│   with cloudflare_calls_turn_app.turn_server,
│   on turn.tf line 16, in resource "cloudflare_calls_turn_app" "turn_server":
│   16: resource "cloudflare_calls_turn_app" "turn_server" {
│ 
│ missing required key_id parameter
╵

Steps to reproduce

1. Prepare terraform configuration as provided.
2. Apply the configuration - this should run fine and create the server. It should be visible in the UI.
3. Run a plan, with or without any changes - this will fail.

Additional factoids

I initially found this bug on terraform version 1.12.2 but it's also reproducible on the newest version. The same error happens if I'm running this on gitlab CI (running on linux).

The key_id that the log complains about is probably the uid that is generated in the resource. I can see that the uid is properly populated in the state but key and key_id stay empty.

{
  "account_id" = "redacted"
  "created" = "2026-01-05T15:22:15Z"
  "key" = (sensitive value) <- this is also tostring(null)
  "key_id" = tostring(null)
  "modified" = "2026-01-05T15:22:15Z"
  "name" = "terraform-test"
  "uid" = "redacted"
}
