Setting 'Network egress' on 'google_storage_bucket' to zero

[tucared]

Hi team,

I would like to submit a suggestion regarding how to handle the Network egress section from the google_storage_bucket ressource: being able to set it to zero.

Currently

Given

• This main.tf file:

  resource "random_id" "bucket_prefix" {
    byte_length = 8
  }
  
  resource "google_storage_bucket" "this" {
    name     = "${random_id.bucket_prefix.hex}-bucket-name"
    location = var.region
  }

• This variables.tf file:

  variable "region" {
    description = "Default region for creating resources"
    type        = string
    default     = "europe-west9"
  }

• This terraform.tfvars file:

  region = "europe-west9"

• This infracost-usage.yml file:

    google_storage_bucket.this:
      storage_gb: 1.5
      monthly_class_a_operations: 2500
      monthly_class_b_operations: 4000
      monthly_data_retrieval_gb: 3750
      monthly_egress_data_transfer_gb:
        same_continent: 0
        worldwide: 0
        asia: 0
        china: 0
        australia: 0

When

I call infracost:

infracost breakdown --path=. \
    --usage-file=infracost-usage.yml \
    --terraform-var-file=terraform.tfvars

Then

I get the following estimate:

 Name                                                                                     Monthly Qty  Unit                      Monthly Cost

    └─ Data transfer to Australia (first 1TB)                                      Monthly cost depends on usage: $0.19 per GB                

We note that Data transfer in same continent item is missing, this behaviour seems to occur to the first item set to 0 in Network egress section of the infracost-usage.yml file.

Suggestion

Since I specified there is no network egress in my usage file, I suggest the output looks as followed:

@tucared thanks for reporting this. This looks like a bug to me. I would expect it to show the following:
