Debug Output

No response

Expected Behavior

After a successful terraform apply, subsequent terraform plan runs should show no diffs.

Actual Behavior

Even after a successful terraform apply, subsequent terraform plan runs continue to show diffs.

Steps to reproduce

1. terraform apply
2. terraform plan

Terraform will perform the following actions:

  # google_cloud_run_v2_service.default will be updated in-place
  ~ resource "google_cloud_run_v2_service" "default" {
        id                      = "projects/frozenbonito-development/locations/us-central1/services/cloudrun-service"
        name                    = "cloudrun-service"
        # (34 unchanged attributes hidden)

      + scaling {
          + min_instance_count = 0
        }

        # (2 unchanged blocks hidden)
    }

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