allTasks.ToJsonStr()

Error message

allTasks.ToJsonStr()

What it means

GetCombineAsync fetches the大会员 (VIP big point) combined task list from the Bilibili API. If the API returns Code != 0 the service throws BiliBusinessException whose message is the entire response serialized to JSON (allTasks.ToJsonStr()). Because the message is the full JSON body, inspect it to find the upstream 'message' field describing the actual failure.

Solutions

1. Update the cookie config with fresh SESSDATA/bili_jct/buvid values.
2. Parse the JSON message in the exception to read the upstream 'message' field and address that specific code.
3. Confirm the account still has大会员 status; the combine endpoint requires it.
4. Wrap the combine task call in try-catch to log and continue with remaining daily tasks.

Example fix

// before
var tasks = await vipBigPointService.GetCombineAsync(ck);
// after
try { var tasks = await vipBigPointService.GetCombineAsync(ck); }
catch (BiliBusinessException ex)
{
    logger.LogWarning("获取大会员任务失败: {Msg}", ex.Message);
}

if (string.IsNullOrWhiteSpace(ck.BiliJct) || string.IsNullOrWhiteSpace(ck.Buvid))
    throw new InvalidOperationException("Cookie缺少 bili_jct 或 buvid，无法获取大会员任务");

try { data = await svc.GetCombineAsync(ck); }
catch (BiliBusinessException ex)
{
    logger.LogWarning("获取任务列表失败: {Msg}", ex.Message);
}

When it happens

Trigger: Calling GetCombineAsync with an expired csrf (BiliJct) or buvid, a non-VIP account, or when Bilibili's VIP task center returns an error code such as not-logged-in (-101) or risk control (-412).

Common situations: Stale cookie after long uptime; account lost VIP status so the VIP task center endpoint rejects the request; Bilibili changed the endpoint or tightened anti-bot checks; buvid missing from the cookie string.
