Genesyscloud_auth_division 409 on apply

Looking for some advice on troubleshooting this weird 409 conflict when applying a new auth division. the resource looks simple enough in hcl. i’ve checked the api directly and the name is unique. no existing division matches. terraform keeps screaming about a conflict.

resource "genesyscloud_auth_division" "test" {
 name = "ops-eu-west"
}

error output says 409 Conflict. any ideas? why is terraform throwing 409 for a new division?
