NotebookLM CreateAudioOverview RPC returned no audio id; ser

Error message

NotebookLM CreateAudioOverview RPC returned no audio id; server may have rejected the request.

What it means

This CommandExecutionError is thrown when the CreateAudioOverview RPC executed but `parseAudioIdFromResult` could not find an audio id in the response, meaning NotebookLM likely rejected or failed the audio-generation request server-side.

Solutions

Retry later — server-side rejections (quota/capacity) are often transient.
Reduce or replace problematic sources, then re-run generate-audio.
Update opencli to a version whose parseAudioIdFromResult matches the current NotebookLM RPC response format, and inspect the RPC result for an embedded error message.

Example fix

// before
const audioId = parseAudioIdFromResult(rpc.result, ids) // null -> throw
// after
if (!rpc.result || rpc.result.error) throw new Error('NotebookLM rejected: ' + JSON.stringify(rpc.result))
const audioId = parseAudioIdFromResult(rpc.result, ids)

Defensive patterns

Strategy: retry

Validate before calling

const sources = await listSources(notebookId);
if (!sources.length) throw new Error('no sources');
if (!supportedLanguages.includes(language)) throw new Error('unsupported language');

Type guard

const hasAudioId = (result) => typeof result?.audioId === 'string' && result.audioId.length > 0;

Try / catch

try {
  return await generateAudio({ notebookId });
} catch (e) {
  if (String(e.message).includes('returned no audio id')) {
    await sleep(60000);
    return await generateAudio({ notebookId });
  }
  throw e;
}

Prevention

Respect NotebookLM audio-overview quotas; space out requests.
Keep opencli current so the RPC response parser matches NotebookLM.
Log the raw rpc.result on failure to capture server-side error messages.

When it happens

Trigger: `callNotebooklmRpc` with NOTEBOOKLM_CREATE_AUDIO_RPC_ID returns a payload from which no audio id can be extracted given the notebookId and sourceIds as context — e.g. quota exceeded, unsupported source types, or NotebookLM RPC format change.

Common situations: Daily audio-overview quota reached; sources too large or unsupported language; NotebookLM silently returning an error body instead of a job id.
