Terraform Configuration Files

terraform {
  required_providers {
    pagerduty = {
      source  = "pagerduty/pagerduty"
      version = ">= 2.2.1"
    }
  }
}

resource "pagerduty_user" "test_user" {
    name  = "Earline Greenholt"
    email = "<EMAIL>"
}

resource "pagerduty_escalation_policy" "escalate_via_email" {
    name     = "Engineering Escalation Policy"
    num_loops = 2

    rule {
        escalation_delay_in_minutes = 10

        target {
            type = "user_reference"
            id   = pagerduty_user.test_user.id
        }
    }
}

resource "pagerduty_service" "dummy_service" {
    name        = "MyDummy"
    description = "PagerDuty service for My Dummy service"
    
    escalation_policy = pagerduty_escalation_policy.escalate_via_email.id

    auto_pause_notifications_parameters {
        enabled = true

    incident_urgency_rule {

        during_support_hours {
            type    = "constant"
            urgency = "low"
        }

        outside_support_hours {
            type    = "constant"

Debug Output

Please provider a link to a GitHub Gist containing the complete debug output: https://www.terraform.io/docs/internals/debugging.html. Please do NOT paste the debug output in the issue; just paste a link to the Gist.

Panic Output

If Terraform produced a panic, please provide a link to a GitHub Gist containing the output of the crash.log.

Expected Behavior

What should have happened?
Terraform plan with no changes in the code should produce no diff

Actual Behavior

What actually happened?
There is a perpetual diff:

Terraform will perform the following actions:

  # pagerduty_service.dummy_service will be updated in-place
  ~ resource "pagerduty_service" "dummy_service" {
        id                      = "PZETJBI"
        name                    = "MyDummy"
        # (11 unchanged attributes hidden)

      ~ incident_urgency_rule {
            # (2 unchanged attributes hidden)

          + during_support_hours {
              + type    = "constant"
              + urgency = "low"
            }

          + outside_support_hours {
              + type    = "constant"
              + urgency = "low"
            }
        }

        # (1 unchanged block hidden)
    }

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