Terraform data source lookup failing on existing flow names

Error: no matching Genesys Cloud routing integration found

Trying to reference an existing routing integration by name in my Terraform module using a data source, but it keeps failing. The resource definitely exists in the UI.

resource "genesyscloud_routing_integration" "test" {
 name = "My Legacy Integration"
}

resource "genesyscloud_routing_integration_setting" "settings" {
 integration_id = data.genesyscloud_routing_integration.existing.id
}

// Data source definition

I’ve tried wrapping the name in quotes and checking for typos. It’s driving me nuts. The docs say it should work, but I’m just getting that ‘no matching’ error. Is there a specific naming convention I’m missing or is the provider just broken for lookups right now?
