HTTP status: 502

What it means

Text-to-speech synthesis failed for a voice element.

• Check the voice element's voiceId against the voice catalog and keep language consistent with the voice.

Example

Every non-2xx response uses the same envelope; path (when present) is the exact JSON path of the offending field, and requestId identifies the request in support conversations:

{
  "error": {
    "code": "TTS_FAILED",
    "message": "Text-to-speech synthesis failed.",
    "docsUrl": "https://automotion.dev/docs/errors/tts_failed"
  },
  "requestId": "req_0123456789abcdef0123456789abcdef"
}

See the error index for the full catalog and the API overview for envelope semantics.
