I’m trying to update an assistant to use a custom Inworld voice, but Vapi returns 400 Bad Request Assistant ID: 13fcc1ad-858e-4582-a68b-ba684dfe46a6 Inworld confirms the voice exists. Payload sent: { "voice": { "provider": "inworld", "voiceId": "voiceidstring", "model": "inworld-tts-1.5-max" } } I also tried adding "languageCode": "en", but it still returned 400. Built-in Inworld voices like Alex work in the same Vapi account, so this seems specific to custom Inworld voice IDs. Can you confirm the correct payload, or check if custom Inworld voice IDs are currently being rejected?
