Terraform re-creates backup selection everytime.

[mukundparmar]

Module version 12.0.0

Terraform apply re-creates the ab_section everytime you run apply.

  # module.aws_backup_vault.aws_backup_selection.ab_selection[0] has been changed
! resource "aws_backup_selection" "ab_selection" {
        id            = "264bce4b-xxxxx-xxxxxxx-xxxxx"
        name          = "default"
+       not_resources = []
        # (3 unchanged attributes hidden)

+       condition {
        }
    }
    
   <skipped> 

  # module.aws_backup_vault.aws_backup_selection.ab_selection[0] must be replaced
-/+ resource "aws_backup_selection" "ab_selection" {
!       id            = "264bce4b-xxxxx-xxxxxxx-xxxxx" -> (known after apply)
        name          = "default"
-       not_resources = [] -> null
        # (3 unchanged attributes hidden)

-       condition { # forces replacement
        }
    }

Plan: 1 to add, 4 to change, 5 to destroy.
   

TF module configuration

module "aws_backup_vault" {

  source  = "lgallard/backup/aws"
  version = "0.12.0"

I guess it's because terraform aws_backup_selection backup requires variable not_resources = [] and conditions. At this moment I can provide only the terraform plan but let me know if you need more information.
