stackit_observability_instance - Provider produced inconsistent result after apply

[docbyte86]

Description

With version 0.65.0 (... and 0.66.0) we are getting error:

│ Error: Provider produced inconsistent result after apply
│ 
│ When applying changes to stackit_observability_instance.observability[0],
│ provider "provider[\"registry.opentofu.org/stackitcloud/stackit\"]"
│ produced an unexpected new value: .alert_config: inconsistent values for
│ sensitive attribute.
│ 
│ This is a bug in the provider, which should be reported in the provider's
│ own issue tracker.

Steps to reproduce

Execute tofu apply with terraform code

@docbyte86 Thank your for the report. We'll take a look at it.

Hi, I also could reproduce the issue. This is I think due to that send_resolved has no default value. @docbyte86 I also think it should be send_resolved = true at least that's what resolved the issue for me. https://github.com/stackitcloud/terraform-provider-stackit/pull/935. Also this is then a breaking upgrade.

Hi, I got the same error on v0.68.0. And it's definitely the variable in the receiver URL. I removed the variable and paste the value direct in the string. It worked without the error.

  alert_config = {
    receivers = [
      {
        name = "OneAlertingReceiver"
        webhooks_configs = [
          {
              send_resolved = true
              url = "https://${var.onealerting_sourcekey}:${var.onealerting_sourcekey}@api.onealerting.schwarz/v1/alert/prometheus"
          }
        ]
      }
    ]
    route = {
      receiver = "OneAlertingReceiver"
      repeat_interval = "4h" # How long to wait before sending a notification again if it has already been sent successfully for an alert. Default 4h
    }
  }

Terraform apply throws the error but it is configured correct in Observability. I checked it with the GET alertconfigs API call.

We are running into the same problem. @rubenhoenle Do you have any ETA?
