Terraform data source lookup by name failing with 'No matching resource found'

I’m trying to reference an existing queue by name using the genesyscloud_routing_queue data source in our Terraform config. I have the name set correctly, but it keeps blowing up with a No matching resource found error during the plan phase. The queue definitely exists in the org, and I’ve checked the spelling multiple times.

Here’s the snippet I’m using:

data "genesyscloud_routing_queue" "support" {
 name = "Customer Support UK"
}

Am I missing a scope parameter or something similar? The docs don’t mention any other required fields for name-based lookups.
