Terraform error on genesys_cloud_routing_queue skills attribute

General Discussion

Applying my queue config fails with a validation error on the skills block. The docs say it expects a list of objects, but the provider keeps rejecting the format.

resource "genesys_cloud_routing_queue" "test_q" {
 name = "Test Queue"
 skills {
 id = "abc-123"
 }
}

Error: Expected a list of objects, got a single object. How do I wrap this correctly?
