Unknown type: ${item.type}

Error message

Unknown type: ${item.type}

What it means

Thrown by the `default` arm of the item-type switch in the Zhihu xhu zhuanlan route. The switch handles known `item.type` values including `zvideo`; any item whose type is not modeled triggers this throw, echoing the type. Like the sibling routes, one unhandled item fails the whole feed.

Solutions

1. Add a `case` for the reported `item.type` that produces a feed entry (reuse the title/link/description mapping pattern).
2. Make `default` skip the unknown item (filter it out) instead of throwing so the rest of the column still renders.
3. Keep this type list in sync with the official `zhuanlan.ts` route (error 673).

Example fix

// before
default:
    throw new Error(`Unknown type: ${item.type}`);
// after — skip unknown items
default:
    return null;

const HANDLED_ZHUANLAN_TYPES = new Set(['article', /* ...existing types... */ 'zvideo']);
function filterZhuanlanItems(items) {
    return items.filter((item) => HANDLED_ZHUANLAN_TYPES.has(item.type));
}

type HandledZhuanlanType = 'article' | 'zvideo'; // extend with actual known set
function isHandledZhuanlanType(item: { type: string }): item is { type: HandledZhuanlanType } {
    return new Set<HandledZhuanlanType>(['article','zvideo']).has(item.type as HandledZhuanlanType);
}

const items = rawItems.filter(isHandledZhuanlanType).map(/* existing mapping */);

When it happens

Trigger: The xhu zhuanlan/column endpoint returns an item whose `type` is outside the handled set — e.g. a new content type the mirror passes through, or a mixed feed where the column surfaces a type the route never encoded.

Common situations: Zhihu or the xhu mirror introduces a new content type surfaced inside a column feed; a type string is renamed; the column aggregates `article` + an unhandled kind. The throw aborts the entire column feed.
