Attempting to transfer a voice call to a specific queue via the Conversations API. Sending the following JSON to PATCH /api/v2/conversations/voice/{conversationId} results in a 422 Unprocessable Entity error with no detail message.

{
“action”: “transfer”,
“target”: {
“type”: “queue”,
“id”: “12345678-1234-1234-1234-123456789012”
}
}

The queue exists and is active. Is the payload structure incorrect for this endpoint?
