Terraform gen_cloud_queue skills attribute failing validation

Context:

Trying to understand why the gen_cloud_queue resource keeps rejecting my skills block. I’ve got a typed Python client that handles the API fine, but the Terraform provider seems stricter than the actual REST endpoint. Here’s the config:

resource "gen_cloud_queue" "main" {
 name = "Support Tier 1"
 skills {
 name = "billing"
 }
}

Running terraform plan throws:
Error: Invalid attribute: An attribute named "skills" is not expected here.

Question:

Is the skills attribute deprecated in the latest provider version or am I missing a nested structure? The OpenAPI spec shows it’s valid for POST /api/v2/routing/queues.
