日报数据不存在或为空

Error message

日报数据不存在或为空

What it means

The AI Base daily route queries an aILogList endpoint and expects `response.data` to be a non-empty array. If the response is falsy or has no `data` property, it throws a generic `Error('日报数据不存在或为空')`. This is a defensive guard against malformed/empty upstream payloads.

Solutions

  1. Retry later — most often this is a transient rate-limit.
  2. Verify the aILogListUrl still returns the expected shape (open it directly).
  3. Inspect the ofetch response status / content-type to distinguish 'empty' from 'blocked'.

Example fix

// before
const response: DailyData = await ofetch(aILogListUrl, { ... });
if (!response || !response.data) throw new Error('日报数据不存在或为空');
// after — surface why it failed
if (!response || !response.data) {
    throw new Error(`aibase daily empty: status=${response?.status ?? 'n/a'}, keys=${Object.keys(response ?? {}).join(',')}`);
}
Defensive patterns

Strategy: retry

Validate before calling

function looksLikeAibaseDaily(r) {
  return r != null && Array.isArray(r.data) && r.data.length > 0;
}

Type guard

function isAibaseDailyPayload(r): r is { data: unknown[] } {
  return !!r && Array.isArray((r as any).data) && (r as any).data.length > 0;
}

Try / catch

let lastErr;
for (let attempt = 0; attempt < 3; attempt++) {
  try {
    const response = await ofetch(aILogListUrl, { query: { pagesize: limit, page: 1, type: 2, isen: 0 }, headers: { accept: 'application/json;charset=utf-8' } });
    if (isAibaseDailyPayload(response)) return response;
    lastErr = new Error('aibase daily empty: ' + JSON.stringify(Object.keys(response ?? {})));
  } catch (e) { lastErr = e; }
  await sleep(1000 * 2 ** attempt); // backoff
}
throw lastErr;

Prevention

When it happens

Trigger: The aILogList API returns an error envelope, an empty payload, or an HTML error page (rate-limit / WAF) that ofetch coerced into an object lacking `data`.

Common situations: Rate-limited by aibase.com; the endpoint path or query contract changed; a WAF/challenge page returned non-JSON.
