Doubao task completed but did not return data.audio_url

Error message

Doubao task completed but did not return data.audio_url

What it means

Raised when the Doubao async TTS polling loop reports task_status == 2 (success) but the returned data object contains no audio_url. The wrapper refuses to continue because the next step downloads the audio from that URL. The literal-brace message never interpolates, so the actual payload is invisible unless you instrument it.

Solutions

1. Persist query_data to a debug log and inspect which keys data actually carries (sometimes the URL moved to data.audio.url or similar)
2. Retry the whole submit — a fresh task usually produces a fresh audio_url
3. Shorten the gap between completion and download by lowering poll_interval_seconds
4. Confirm the resource_id/endpoint pairing matches the current Volcengine console

for attempt in range(2):
    try:
        result = doubao_tool.execute(inputs)
        break
    except RuntimeError as e:
        if "audio_url" in str(e) and attempt == 0:
            continue  # re-submit: completed task lost its artifact
        raise

When it happens

Trigger: QUERY_URL returns status 2 with data.audio_url missing/null/empty — expired or purged audio, partial server-side success, or an envelope change in the query response.

Common situations: Long polls where the audio expired between completion and query; region/console migration altering the response schema; account state (quota exhausted mid-task) producing a 'succeeded' status with no artifact.
