Terraform for_each with YAML variables fails on Genesys queues

General Discussion

Why is this setting causing a parsing error when I try to map YAML keys to Genesys Cloud queues?

Background
I am building a CX as Code pipeline. I need to create multiple queues from a single YAML variable file. I am using the Terraform Provider for Genesys Cloud. I want to use for_each to iterate over the YAML data. My YAML file (queues.yaml) looks like this:

queues:
 sales_us:
 name: "Sales US"
 description: "US Sales Team"
 support_eu:
 name: "Support EU"
 description: "EU Support Team"

Issue
I load the YAML into Terraform using yamldecode(file("queues.yaml")). I then pass this to for_each. However, the genesyscloud_routing_queue resource fails during terraform plan.

locals {
 queue_data = yamldecode(file("queues.yaml"))
}

resource "genesyscloud_routing_queue" "example" {
 for_each = local.queue_data.queues
 name = each.value.name
}

The error message is: Invalid index. An object with no attribute collection is not addressable.

Troubleshooting

  1. I checked the YAML syntax. It is valid.
  2. I printed local.queue_data.queues and it shows a map of objects.
  3. I tried using keys() but it does not help with the value access.

How do I correctly structure the for_each loop to handle this nested YAML structure?
