Genesyscloud_messaging_application 409 Conflict on AU-1 BYOC Terraform Apply

Can anyone clarify the expected behavior for messaging application provisioning when the underlying WhatsApp provider is already linked?

Running into a 409 Conflict error during terraform apply on our AU-1 BYOC instance. The provider version is v1.15.0. The error response indicates that a messaging application with the specified provider ID already exists, yet no resource is visible in the Genesys Cloud UI under Digital > Messaging.

The HCL snippet is minimal:

resource "genesyscloud_messaging_application" "whatsapp_prod" {
 provider_id = var.whatsapp_provider_id
 name = "WhatsApp Prod Channel"
 enabled = true
}

The provider_id is valid and confirmed via genesyscloud_messaging_provider data source. A manual GET request to /api/v2/messaging/applications returns an empty array. This suggests a state drift or a backend orphaned record.

Has anyone encountered this specific 409 on AU-1 BYOC? Is there a force-delete API endpoint to clear the ghost record, or should we wait for a TTL expiration? The deployment pipeline is blocked.
