Selecting Backups By Conditions: AWS_Backup_Selection returns unexpected block

[oldManLemon]

Issue

Just following the instructions for creating a condition based backup lifecycle in AWS, when I attempt to use the condition block which is referenced in the documentation it returns an error stating the condition block was not expected?

https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/backup_selection#selecting-backups-by-conditions

Terraform CLI and Terraform AWS Provider Version

Affected Resource(s)

• aws__Backup_Selection

Terraform Configuration Files

There are more but at this point even the example is just returning the error

resource "aws_backup_selection" "our_chosen_resources" {
  iam_role_arn = aws_iam_role.aws_backup_role.arn
  name         = "my_selected_resources"
  plan_id      = aws_backup_plan.daily_backup_rention_policy.id

  condition {
    string_equals {
      key   = "aws:ResourceTag/Component"
      value = "rds"
    }
    string_like {
      key   = "aws:ResourceTag/Application"
      value = "app*"
    }
    string_not_equals {
      key   = "aws:ResourceTag/Backup"
      value = "false"
    }
    string_not_like {
      key   = "aws:ResourceTag/Environment"
      value = "test*"
    }
  }
}

Debug Output

Panic Output

Expected Behavior

Accepts the existence of the condition code block

@oldManLemon Thanks for raising this issue. Which version of the Terraform AWS Provider are you using? The aws_backup_selection.condition block was added in v3.72.0.

I came across this issue and having the wrong pinned version for hashicorp/aws was the problem. Updating to the latest did the trick for me.
