Invalid taskCode

Error message

Invalid taskCode: {taskCode}

What it means

CompleteViewAsync maps a VIP viewing task code (taskCode) to a channel via a switch expression; any taskCode other than 'animatetab' or 'filmtab' throws ArgumentOutOfRangeException with 'Invalid taskCode: {taskCode}'. This is a local guard against calling the view-completion flow with an unsupported task identifier.

Solutions

1. Only pass 'animatetab' or 'filmtab' to CompleteViewAsync; route other task codes to CompleteV2Async instead.
2. Add the new tab code to the switch mapping if Bilibili introduced one (e.g. "newtab" => "new_channel").
3. Log the full task list from GetCombineAsync and pick codes the service explicitly supports.
4. Validate taskCode before calling to avoid an unhandled exception in the daily run.

Example fix

// before
await service.CompleteViewAsync("viewcomplete", ck);
// after
if (taskCode is "animatetab" or "filmtab")
    await service.CompleteViewAsync(taskCode, ck);
else
    await service.CompleteV2Async(taskCode, ck);

private static readonly HashSet<string> SupportedViewTaskCodes = new() { "animatetab", "filmtab" };
if (!SupportedViewTaskCodes.Contains(taskCode))
{
    logger.LogWarning("跳过不支持的任务Code: {TaskCode}", taskCode);
    return false;
}

try { await svc.CompleteViewAsync(taskCode, ck); }
catch (ArgumentOutOfRangeException)
{
    logger.LogWarning("任务Code {TaskCode} 不支持浏览完成，改用CompleteV2Async", taskCode);
    await svc.CompleteV2Async(taskCode, ck);
}

When it happens

Trigger: Calling CompleteViewAsync directly with a taskCode string obtained from a different task list (e.g. 'viewcomplete' or a numeric code) that isn't one of the two supported viewing tabs, or after Bilibili introduces a new tab code the mapping doesn't handle.

Common situations: Custom task automation passing codes from GetCombineAsync's task list; Bilibili renaming/adding tab codes upstream; typo in the taskCode string when wiring up tasks manually.

Understand the failure class

Background: Invalid enum value errors: "Unknown type", "Invalid scope", "must be one of" — when a string is not on the library's allowed list — this error's family across 23 libraries.
