Script node type mismatch 400 via Terraform

Just noticed that the script deployment fails with a 400 Bad Request when defining a TTS node. Provider v1.65.2. Region au-1. The HCL validates but the API rejects the node_type field.

resource “genesyscloud_script” “test” {
name = “tts_test”
script_nodes {
type = “TTS”
tts_text = “hello”
}
}

Error: 400 Bad Request - Invalid node type. Is the TTS type deprecated in this provider version?
