Unsupported argument output

I have the next config.






on main I have

module "vpc" {
  source = "./modules/vpc"

module "compute_engine_controller" {
  source = "./modules/compute_engine"
  vpc_name = module.vpc.vpc_network_name

on vpc I have

output "vpc_network_name" {
  value = google_compute_network.vpc_network.name

on ce I have

resource "google_compute_instance" "controller" {
  network_interface {
    network = var.vpc_name

I get an error

│ Error: Unsupported argument

│ on main.tf line 34, in module "compute_engine_controller":
│ 34: vpc_name = module.vpc.vpc_network_name

│ An argument named "vpc_name" is not expected here.


>Solution :

Since the module is complaining about not expecting an argument called vpc_name, that means that the corresponding variable has not been defined in the variables.tf of the module. To fix this, what needs to be added is:

variable "vpc_name" {
  type        = string
  description = "The name of the VPC to be used."
