Error message

暂无前瞻直播资讯！

What it means

A generic Exception from GetCodeMsgAsync thrown when both GetActIdAsync('1') and GetActIdAsync('2') return an empty actId. It means no livestream (前瞻直播) activity is currently registered in the upstream data source, so redeem codes cannot be fetched. This is a data-availability condition, not a parse error.

Solutions

1. Retry later when a 前瞻直播 (special program) is actually airing or has aired recently.
2. Verify network connectivity and that the upstream API endpoints are reachable.
3. Catch the exception at the UI boundary and show a user-facing 'no codes available yet' message rather than an error.
4. Confirm the API base URLs and actId slots in GetActIdAsync still match the upstream contract.

Example fix

null

var actId = await GetActIdAsync("1");
if (string.IsNullOrEmpty(actId)) actId = await GetActIdAsync("2");
if (string.IsNullOrEmpty(actId)) { /* show 'no codes yet' and stop */ }

null

try { var codes = await svc.GetCodeMsgAsync(); }
catch (Exception ex) { Toast.Warning(ex.Message); /* 'no codes yet' */ }

When it happens

Trigger: Calling GetCodeMsgAsync outside the livestream reveal window, or when the upstream miHoYo/HoYoLAB activity index has no current act entry for either id slot. Both actId lookups returning empty trips the throw.

Common situations: Running the redeem-code feature when no special-program livestream is active; upstream API change that moved the actId; regional availability (the codes may exist only in CN); rate limiting or transient empty response interpreted as 'no data'.
