NotebookLM CreateArtifact (slides) RPC returned no slide-dec

Error message

NotebookLM CreateArtifact (slides) RPC returned no slide-deck id; the server may have rejected the request.

What it means

This CommandExecutionError is thrown when the CreateArtifact (slides) RPC ran but `parseSlidesIdFromResult` could not extract a slide-deck id from the response, indicating NotebookLM likely rejected the slide-generation request server-side.

Solutions

Retry after a delay (quota/capacity rejections are transient).
Adjust options (fewer sources, supported language, standard --length) and re-run.
Update opencli so parseSlidesIdFromResult matches the current NotebookLM response shape; inspect the raw rpc.result for an error message.

Example fix

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

Defensive patterns

Strategy: retry

Validate before calling

const sources = await listSources(notebookId);
if (!sources.length) throw new Error('no sources');
if (!Number.isInteger(length) || length <= 0) throw new Error('bad --length');

Type guard

const hasSlidesId = (result) => typeof result?.slidesId === 'string' && result.slidesId.length > 0;

Try / catch

try {
  return await generateSlides({ notebookId, length });
} catch (e) {
  if (String(e.message).includes('returned no slide-deck id')) {
    await sleep(60000);
    return await generateSlides({ notebookId, length });
  }
  throw e;
}

Prevention

Respect NotebookLM generation quotas; throttle requests.
Use supported languages and standard lengths.
Update opencli so the slides-id parser tracks the current RPC response format.

When it happens

Trigger: `callNotebooklmRpc` with NOTEBOOKLM_CREATE_ARTIFACT_RPC_ID returns a payload without a parseable slides id — quota limits, unsupported sources/language, invalid --length for the server, or an RPC response format change.

Common situations: Daily generation quota exhausted; requested deck length/language unsupported; NotebookLM returning an error payload the parser cannot read.
