Timeout when instance_group_manager is run

[Logan-Kang]

Hello

I git clone this code and upgraded it to 0.12
The upgrade to 0.12 removed the unnecessary update_strategy, rolling_update_policy. Then, the test was conducted, and the generation was stopped due to timeout while performing instance_group_manager.
After that, timeout occurs continuously in the refreshing state even if I perform the terraform apply or terraform destroy again.

module "mig1" {
source = "../../"
module_enabled = var.module_enabled
region = var.region
zone = var.zone
zonal = true
name = var.network_name
machine_type = "n1-standatd-1"
size = 3
target_tags = [var.network_name]
service_port = 80
service_port_name = "http"
startup_script = data.template_file.startup-script.rendered
wait_for_instances = true

network = google_compute_subnetwork.default.name
subnetwork = google_compute_subnetwork.default.name
instance_labels = var.labels
http_health_check = var.http_health_check

/* update_strategy = "ROLLING_UPDATE"

rolling_update_policy = [

{

type = "PROACTIVE"

minimal_action = "REPLACE"

max_surge_fixed = 4

max_unavailable_fixed = 4

min_ready_sec = 50

},
