Ctrip round-trip flight cards rendered but parser did not fi

Error message

Ctrip round-trip flight cards rendered but parser did not find required flight anchors

What it means

A CommandExecutionError thrown when the page DID render the expected number of flight cards (renderedCardCount > 0) but the extraction script still produced an empty rows array — i.e. the parser's required flight anchors were not found inside the rendered cards. This is a targeted parser/selector mismatch signal, not an absence of data.

Solutions

1. Upgrade the library — this signature means a selector/anchor update is likely needed.
2. Retry later in case an A/B variant was serving a different layout.
3. Inspect the rendered cards in DevTools and report which anchors are missing to maintainers.
4. Force a consistent locale/variant by reusing a logged-in browser profile where the standard layout renders.

Example fix

// before
npm ls && cli flight-round ...  # old broken version
// after
npm update opencli && cli flight-round --from PEK --to SHA --depart ... --return ...

function isAnchorParseFailure(e) { return e && String(e.message || '').includes('did not find required flight anchors'); }

try { return await runFlightRound(args); }
catch (e) {
  if (isAnchorParseFailure(e)) { const fresh = await newBrowserSession(); return await runFlightRound(args, fresh); }
  throw e;
}

When it happens

Trigger: buildScrollUntilJs confirms ROUND_CARD_SELECTOR matched rendered cards on the round-trip page, but buildFlightExtractJs returns [] because the anchor fields it looks for inside each card are missing or renamed.

Common situations: Ctrip redesigned card internals (class names, data attributes) while keeping the card selector valid; A/B test variant serving a different card layout; lazy-rendered inner fields not present at extraction time.
