Error message

Failed to parse visible Weibo favorites

What it means

clis/weibo/favorites.js:160 throws CommandExecutionError('Failed to parse visible Weibo favorites') when raw cards were found but every one failed parseFavoriteCard/dedupeFavorites, leaving zero unique items. It signals the page had content the parser could not understand, as opposed to a genuinely empty page.

Solutions

1. Update the CLI to the latest version — this usually means the page markup changed
2. Open weibo.com/fav in Chrome and inspect the card text to confirm the layout the parser expects
3. Retry later; if Weibo was mid-deploy the old layout may return
4. File a bug with a sample card text if the latest version still fails to parse

Example fix

// before: hard failure on redesign
const favs = await cli.run('weibo favorites', { limit });
// after: degrade gracefully
let favs = [];
try { favs = await cli.run('weibo favorites', { limit }); }
catch (e) { console.warn('favorites parse failed; possibly Weibo markup change:', e.message); }

function isParseFailure(e) { return e instanceof Error && e.message === 'Failed to parse visible Weibo favorites'; }

let favorites = [];
try {
  favorites = await cli.run('weibo favorites', { limit });
} catch (e) {
  if (isParseFailure(e)) {
    console.warn('Weibo favorites page could not be parsed — CLI may need updating; continuing with empty result.');
  } else throw e;
}

When it happens

Trigger: rawData is non-empty but each card's text lacks the expected fields (author/time/content lines), so parseFavoriteCard returns falsy for all cards, or dedupeFavorites removes everything because favUrl matching fails.

Common situations: Weibo changing the favorites-page DOM/text layout after an update; cards being ads, headers, or tab elements rather than actual favorite entries; locale/time-format changes breaking the regex heuristics; running an outdated CLI against a redesigned page.
