Error message

sinafinance rolling-news

What it means

EmptyResultError('sinafinance rolling-news') thrown when the rolling news API succeeds (status 0, data is an array) but contains zero items. This is a typed empty-result signal so callers can distinguish 'no news right now' from failures.

Solutions

1. Remove or widen page/time parameters to request the default window
2. Retry later — the feed may simply have no items yet
3. Treat as an expected empty state in automation rather than an error
4. Fall back to the regular news command for broader coverage

try {
  const rows = await cli.rollingNews();
} catch (err) {
  if (err instanceof EmptyResultError || /rolling-news/.test(err.message)) {
    return []; // expected empty state, not a failure
  }
  throw err;
}

When it happens

Trigger: Fetching rolling news when Sina's feed has no entries for the requested time window/page — e.g. requesting page N beyond available results, or an extremely narrow time range with no published items.

Common situations: Paging past the end of available rolling news; querying during a quiet period (overnight/holiday) with filters that exclude everything; automated jobs polling a specific window that has no items.

Understand the failure class

Background: EmptyResultError / "no results found": when an API or scraper succeeds but returns zero rows — this error's family across 9 libraries.
