could u confirm where the fields and types of network output are checked from? from /outputs.tf
output "network" {
value = module.vpc
description = "The created network"
}

and module.vpc point to
modules/vpc/outputs.tf:

output "network" {
value = google_compute_network.network
description = "The VPC resource being created"
}

and some fields here are not present in resource "google_compute_network" "network" { ...} at modules/vpc/main.tf like gateway_ipv4

are these fields of network output type verified from terraform apply results of this module?

why are empty values in type added for some output types like subnets, subnets_flow_logs etc
