Error message

re.ToJsonStr()

What it means

SignAsync performs the daily VIP check-in via Sign2Async. On a non-zero API code it throws BiliBusinessException containing the full response JSON (re.ToJsonStr()). The check-in endpoint requires valid login cookies; failures are almost always authentication or risk-control responses from Bilibili.

Solutions

1. Refresh the BiliBiliCookies config value with a newly exported cookie.
2. Read the JSON in the exception message for the upstream code/message (-101 => re-login, -412 => reduce frequency/change IP).
3. Ensure only one instance of the scheduled tool runs per account.
4. Catch BiliBusinessException around sign tasks so other daily tasks still execute.

Example fix

// before
await vipBigPointService.SignAsync(dailyTaskInfo, ck);
// after
try { await vipBigPointService.SignAsync(dailyTaskInfo, ck); }
catch (BiliBusinessException ex)
{
    logger.LogWarning("大会员签到失败: {Msg}", ex.Message);
}

if (string.IsNullOrWhiteSpace(ck.Sessdata) || string.IsNullOrWhiteSpace(ck.BiliJct))
    logger.LogWarning("Cookie不完整，签到大概率失败");

try { await svc.SignAsync(info, ck); }
catch (BiliBusinessException ex)
{
    logger.LogWarning("签到失败: {Msg}", ex.Message);
}

When it happens

Trigger: Expired SESSDATA/bili_jct in the cookie, Bilibili returning -101 (not logged in) or -412 (risk control) for the sign endpoint, or calling sign twice in a day if the API rejects duplicate signs with an error code.

Common situations: Daily cron run with a stale cookie; account flagged by anti-bot after frequent requests; multiple instances of the tool signing with the same account causing conflicts.
