Google Compute Instance Alias IP range - Unsupported argument issues

Terraform HCP Terraform
1

I am using Google Cloud Provider version 3.37.0
Terraform version 0.13.4

I am trying to deploy a google compute instance resource with some “alias_ip_range” configuration.
Here is my code sample:

 resource "google_compute_instance" "default" {
          name         = "test"
          machine_type = "n1-standard-1"
          zone         = "europe-west2-b"

      tags = concat(var.tags,["loo"])

      boot_disk {
        initialize_params {
          image = "debian-cloud/debian-9"
        }
      }


      network_interface {
        network = "default"
        subnetwork = "default"

       # access_config {
       #   // Ephemeral IP
       # }

        alias_ip_range = [
          {
            ip_cidr_range = "/32"
          },
          {
            ip_cidr_range  = "/32"
          }
        ]
      }

      metadata = {
        foo = "bar"
      }

      service_account {
        scopes = [ "compute-ro", "storage-ro"]
      }
    }

I am getting this error during the deployment:

An argument named “alias_ip_range” is not expected here. Did you mean to
define a block of type “alias_ip_range”?

Any help why is this format declaration wrong?
