What causes "Bilibili has not generated an AI summary for ${bvid}." in jackwener/OpenCLI?

Handle EmptyResultError as an expected outcome — skip the video or fall back to your own summarization (e.g. fetch subtitles and summarize locally).

Bilibili has not generated an AI summary for ${bvid}.

Error message

Bilibili has not generated an AI summary for ${bvid}.

What it means

readModelResult() throws this EmptyResultError when the conclusion endpoint reports data.code !== 0 for the requested video — Bilibili's signal that no AI summary has been generated for that video (not all videos have one; generation depends on duration, content, and availability). It is an expected empty result, not a crash: the library surfaces it so callers can fall back to another summarization method.

Solutions

Handle EmptyResultError as an expected outcome — skip the video or fall back to your own summarization (e.g. fetch subtitles and summarize locally).
Retry later: summaries are generated asynchronously and may appear after a delay for new uploads.
Check the video page in a browser to confirm whether an AI summary exists.
If running batch jobs, pre-filter videos known to lack summaries to reduce noise.

Example fix

// before
const summary = await runSummaryCommand(bvid); // throws EmptyResultError
// after
try {
  const summary = await runSummaryCommand(bvid);
} catch (e) {
  if (isEmptyResult(e)) return fallbackLocalSummary(bvid);
  throw e;
}

Defensive patterns

Strategy: fallback

Try / catch

try {
  return await summaryCommand(bvid);
} catch (e) {
  if (e.name === 'EmptyResultError' || /has not generated an AI summary/.test(e.message)) {
    return localFallbackSummary(bvid); // e.g. fetch subtitles and summarize
  }
  throw e;
}

Prevention

Treat missing AI summaries as normal for short/new videos — build a fallback path.
For fresh uploads, retry after a delay before giving up.
When batching, catch EmptyResultError per video instead of aborting the whole run.
Verify in a browser whether the video shows an AI summary before reporting it as a bug.

When it happens

Trigger: Querying the conclusion API for a short video, a newly uploaded video, an audio/管理-type submission, or any video for which Bilibili has not produced the AI 总结 — the payload carries data.code non-zero (e.g. -400 request OK but no summary) and readModelResult at summary.js:76-78 converts it to EmptyResultError.

Common situations: Batch-summarizing videos where some simply lack AI summaries; summarizing very fresh uploads minutes after publish; videos where the AI summary feature was disabled; users expecting every video to have a summary.
