Error message

could not find video in page

What it means

bilibili.extractFestival handles festival/activity pages. It matches the whole script tag containing window.__INITIAL_STATE__ and this error fires when the outer script regex matched but the capture group is absent (len(matches[0]) < 2), i.e. the festival page has no extractable video state. It is distinct from the sibling ErrURLParseFailed check one line above, which fires when no script matched at all.

Solutions

1. Confirm the festival URL still shows its video in an incognito browser.
2. If the event ended, locate the underlying av/BV id in the page and extract that video URL directly.
3. Retry with a cookie (-c) to bypass risk control.
4. If the page format changed, update the extractFestival script regex.

Example fix

// before
$ lux "https://www.bilibili.com/festival/2022bnj?bvid=BV1er411b7mJ"
// after — extract the underlying video id directly
$ lux "https://www.bilibili.com/video/BV1er411b7mJ"

func isFestivalVideoMissing(err error) bool {
	return err != nil && strings.Contains(err.Error(), "could not find video in page")
}

Catch and, when this specific message appears, retry once with the underlying av/BV video URL extracted from the festival page; otherwise surface the error with the original festival link for manual triage.

When it happens

Trigger: A /festival/ URL whose activity ended and now redirects elsewhere; a festival template without the __INITIAL_STATE__ script payload; a risk-control page served instead of the festival DOM.

Common situations: Expired seasonal event links (the most common case); Bilibili template changes; scraping from flagged IPs.
