Class TextToSpeechError

The whole error envelope or frame the API sent.

The WebSocket close code that ended a session; see errorCode for the codes.

The API's stable code, the same on HTTP and on a session. Among them:

• invalid_parameter (422; close 3006): param and errors say which field.
• rate_limited (429, retryable; close 3009): wait retryAfter seconds.
• voice_not_found (422; close 3012, param: "voice_id").
• voice_expired (422; close 3012, param: "voice_id"): the cloned voice's consent period ended; its owner can create it again from a new recording.
• voice_not_paired (422; close 3014, param: "model_id"): the cloned voice is not paired with the model, or the pairing is still in progress.
• not_owner (422; close 3006, param: "extend_biometric_consent"): extend_biometric_consent on a voice another account owns.
• biometric_terms_not_accepted (403, not retryable; close 3006, param voice_id or extend_biometric_consent): the account has not accepted the biometric data terms that its own cloned voices and extend_biometric_consent need; accept them on the data controls page of the AssemblyAI dashboard.
• auth_unavailable (503, retryable; close 1011): the credential, or the account's biometric data terms, could not be checked just now.

Absent on a refusal of createTemporaryToken(), whose message carries the token service's reason.

For invalid_parameter, every failing field.

The field at fault, if one.

The request's id; on a session, the session's id from Begin, so a session refused before Begin has none: read errorCode and closeCode.

Whether the same request, or a new session, can succeed later.

Seconds to wait before retrying, when the API said.

The HTTP status. On a session, only a refused WebSocket upgrade has one, and only where the runtime reports it (Node does, a browser does not).
