Error message

dianping ${contextHint}

What it means

The final fallback of detectAuthOrPageFailure: when the page matched neither captcha nor login patterns and none of the caller-supplied emptyPatterns matched, it throws EmptyResultError('dianping <contextHint>') if an empty pattern did match, and otherwise CommandExecutionError 'did not render expected data'. EmptyResultError here means the page genuinely rendered but contained no matching data — dianping returned an empty result set for the query.

Solutions

1. Broaden the search keyword or remove filters and retry.
2. Check the cityId: resolveCityId maps names to ids; try the shop's actual city or omit it to use the cookie's default city.
3. Verify the shop id still exists by opening www.dianping.com/shop/<id> in a browser.
4. Treat it as an expected empty result if your query is legitimately unmatched — the CLI throws EmptyResultError so scripts can skip it (catch and continue).

Example fix

// before
await search({ city: 'xiamen', keyword: 'deep dish pizza' }); // EmptyResultError
// after
try {
  await search({ city: 'xiamen', keyword: 'pizza' });
} catch (err) {
  if (err.code === 'EMPTY_RESULT') return []; // expected: no matches
  throw err;
}

function isEmptyResultError(err) {
  return err instanceof Error && err.code === 'EMPTY_RESULT';
}

try {
  results = await dianpingSearch(args);
} catch (err) {
  if (err.code === 'EMPTY_RESULT') {
    results = []; // expected: no data for this query
  } else throw err;
}

When it happens

Trigger: A dianping search/detail step whose rendered HTML matches one of the emptyPatterns regexes passed by the adapter — e.g. searching a keyword with zero shops in the chosen city, a category filter with no matches, or a deleted/closed shop page.

Common situations: Overly narrow search keywords, mismatched cityId vs keyword (shops only exist in another city), filters (price/cuisine/district) that exclude all results, or a shop that has closed since the id was collected.

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.
