Sina Finance rolling news API returned malformed data

Error message

Sina Finance rolling news API returned malformed data

What it means

CommandExecutionError thrown by normalizeRollRows when payload.result.data is not an array. The library guards against Sina changing the response shape (or an error page being parsed) so map() doesn't crash on undefined. It indicates the response passed the status check but the data field is missing or of the wrong type.

Solutions

1. Log the full raw payload to inspect the actual response shape
2. Check if Sina changed the API response structure and update the CLI
3. Bypass proxies/VPN to rule out payload rewriting
4. Pin/report the issue so the parser is updated to the new schema

Example fix

// before
const items = payload?.result?.data; // now an object {list: [...]}
// after
const items = payload?.result?.data?.list ?? payload?.result?.data;

function hasRollDataArray(payload) {
  return Array.isArray(payload?.result?.data);
}

try {
  const rows = await cli.rollingNews();
} catch (err) {
  if (/returned malformed data/.test(err.message)) {
    // response shape changed; dump raw payload for diagnosis
    console.error('Sina rolling news schema changed? Inspect raw payload');
  }
  throw err;
}

When it happens

Trigger: The rolling news API returns status.code === 0 but result.data is undefined, an object, or null — typically after a Sina API schema change, or an intermediary (proxy/captive portal) injecting content.

Common situations: Sina silently upgrading their API and relocating the data array; a corporate proxy returning a rewritten payload with status code 0; caching layers returning stale/different schemas.

Understand the failure class

• Parsing and encoding errors: unexpected token, malformed input — why parsers reject input and how to find the real culprit.
