Genesyscloud_ai_bot 400 on intent training data via Terraform

Can’t quite understand why the AI bot resource fails during intent training data upload. The payload is valid JSON, but the API rejects it with a 400.

env: us-1 prod
provider: genesys 1.15.4
tf: 1.6.5

resource “genesyscloud_ai_bot” “main” {
name = “CX-Bot-Prod”
language = “en-US”
intent {
name = “check_balance”
training_phrases = [
“what is my balance”,
“show balance”
]
}
}

POST /api/v2/analytics/bots returns 400. Error: “training_phrases format invalid”.
