Trip.com transfer cards rendered but parser did not find req

Error message

Trip.com transfer cards rendered but parser did not find required price anchors

What it means

CommandExecutionError thrown when transfer cards visibly rendered and the extractor returned an array, but the array is empty: the parser found no required price anchors inside the cards. Layout changed enough to keep card containers but break the price element the extractor depends on.

Solutions

1. Inspect the rendered cards in DevTools and update the price-anchor selector in buildTransferExtractJs()
2. Add a scroll/interaction step to trigger lazy price rendering before extraction
3. Confirm the market/currency (via --country or cookies) shows list prices
4. Capture a screenshot/DOM snapshot on this error to speed up future selector fixes

Example fix

// before
const raw = await page.evaluate(buildTransferExtractJs());
// after
await page.evaluate(() => window.scrollTo(0, document.body.scrollHeight));
await page.waitForTimeout(1500);
const raw = await page.evaluate(buildTransferExtractJs());

// before extraction, ensure prices had a chance to lazy-load
await page.evaluate(() => window.scrollTo(0, document.body.scrollHeight));
await page.waitForTimeout(1500);

function hasPriceAnrows(v) { return Array.isArray(v) && v.length > 0; }

try {
  const rows = await getTransfers(args);
} catch (e) {
  if (e.message.includes('price anchors')) {
    console.error('Prices lazy-load or UI changed; try scroll-before-extract or update selector');
  }
  throw e;
}

When it happens

Trigger: Trip.com moves prices behind a lazy-loaded component, swaps price elements for a new component (e.g. 'from $X' badge), or gates prices behind a currency/region selection, so the extractor's price-anchor selector matches zero nodes.

Common situations: New Trip.com pricing UI; prices only render after interaction (hover/scroll); currency-selection interstitial; regional variant of the page without list prices.
