Error message

暂不支持对${type}的订阅

What it means

Thrown as an `InvalidParameterError` when the `type` path parameter for the NUA Library route does not match any of the supported `case` branches. The switch assigns `webPageName` CSS selectors for specific library navigation categories (like djdt, zydt, fwdt), and the default branch throws.

Solutions

1. Check the switch cases in `lib/routes/nua/lib.ts` for the complete list of supported type values (includes 'djdt', 'zydt', 'fwdt', and others above).
2. Browse the NUA library website to identify the correct type identifier.
3. Add a new `case` branch if the library added a new category.

// Validate type against known switch cases
const validLibTypes = new Set(['xwgg', 'djdt', 'zydt', 'fwdt' /* ...all case labels */]);
if (!validLibTypes.has(type)) {
    throw new InvalidParameterError(`暂不支持对${type}的订阅`);
}

function isSupportedLibType(type: string): boolean {
    return ['xwgg', 'djdt', 'zydt', 'fwdt'].includes(type);
}

When it happens

Trigger: A user requests the NUA library route with a `type` value not among the predefined cases (which map to `.wp_column.column-N.selected` selectors). The type determines which news category page to scrape from the NUA library site.

Common situations: User passes an unsupported type value. The library website restructured its column layout. A bookmarked URL references an old type that was removed from the switch.
