Error message

re.Message

What it means

GetRandomArticleFromUp calls SearchUpArticlesByUpIdAsync and throws BiliBusinessException carrying the API's own message when the response Code != 0, surfacing Bili server-side failures (e.g. no results, risk control, auth issues) to the caller.

Solutions

1. Read the exception message — it is the raw Bili API message — and address the indicated cause (usually re-auth with a fresh cookie).
2. Verify the target up actually has published articles before invoking this flow.
3. Add pacing/backoff to reduce risk-control and rate-limit responses.
4. Update to the latest library version if Bili changed the search API contract.

Example fix

// before
var article = await articleDomainService.GetRandomArticleFromUp(upId, cookie);
// after (guard with try-catch and fallback)
try { var article = await articleDomainService.GetRandomArticleFromUp(upId, cookie); }
catch (BiliBusinessException ex) { logger.LogWarning("文章搜索失败: {0}", ex.Message); /* fallback */ }

// ensure cookie is valid and the up has articles before the call
if (string.IsNullOrWhiteSpace(upId)) throw new ArgumentException("upId is required");

try { var article = await svc.GetRandomArticleFromUp(req); }
catch (BiliBusinessException ex)
{
    logger.LogWarning("Bili API 返回错误: {Msg}", ex.Message);
    // apply fallback: skip article task or retry later
}

When it happens

Trigger: Any call where the search-up-articles API returns a non-zero code: invalid/insufficient cookie privileges, Bili risk control, target up has no visible articles, or transient Bili API errors.

Common situations: Running without valid login for endpoints that require it; requesting articles of an up whose article list is empty or hidden; Bili API changes/deprecations; heavy automated usage triggering rate limits.
