Bug: instana_application_alert_config gets timeouts on plans and applys

[cloiselet-lp]

Hello !

I'm using this provider to handle my Instana configuration, and I found that the instana_application_alert_config does not behave as expected :

• It took 20+ minutes to create 6 alerts according to Terraform; I could see the alerts in Instana from the minute 5.
• Once the alerts are created, Terraform can no longer run plans; The plan is waiting for the instana_application_alert_config indefinitly, until it reaches its timeout.

I am using the v3.3.0 version of the provider.

The resource I am creating is this one :

resource "instana_application_alert_config" "production_errors" {
  for_each = { for app, details in instana_application_config.applications : app => details if strcontains(app, "production") }

  name        = "${each.key} - Erroneous call rate is higher than normal"
  description = "The erroneous call rate for the specified application is higher or equal than expected. This may mean that users are encountering issues using the application."

  boundary_scope    = "ALL"
  severity          = "warning"
  include_internal  = false
  include_synthetic = false

  alert_channel_ids = [
    instana_alerting_config.infrastructure.id
  ]

  granularity     = 600000
  evaluation_type = "PER_AP"

  application {
    application_id = each.value.id
    inclusive      = true
  }

  rule {
    errors {
      aggregation = "MEAN"
      metric_name = "errors"
    }
  }

  threshold {
    historic_baseline {
      operator = ">="
      # baseline
      deviation_factor = 3
      seasonality      = "WEEKLY"
    }
  }

  time_threshold {
    violations_in_sequence {
      time_window = 600000
    }
  }

  lifecycle {
    ignore_changes = [
      # the baseline is dynamic and will change over time, so we need to ignore it.
      threshold[0].historic_baseline[0].baseline,
      threshold[0].historic_baseline[0].last_updated,
    ]
  }
}

The logs I can extract from these run only show that the plan is starting on this component, no updates after this.
