Unknown category: ${category}

Error message

Unknown category: ${category}

What it means

Thrown by the UW Global Innovation Exchange (GIX) news route when the `category` path parameter does not match `blog` or `inthenews`. Unlike other USTC/UW routes, the `category` parameter here is required (no default) — the path is `/gix/news/:category` with no `?`. This is a generic `Error`, not an RSSHub typed error.

Solutions

1. Use exactly `blog` or `inthenews` as the category (case-sensitive, lowercase).
2. Check the route's description table for the valid category codes.
3. If you need a category that doesn't exist, the source site (gixnetwork.org) may not provide an RSS-compatible feed for it.

Example fix

// before
GET /uw/gix/news/press
// after
GET /uw/gix/news/inthenews

const VALID_CATEGORIES = ['blog', 'inthenews'];
if (!VALID_CATEGORIES.includes(category)) {
    throw new InvalidParameterError(`Unknown category: ${category}. Valid: ${VALID_CATEGORIES.join(', ')}`);
}

function isValidGixCategory(c: string): c is 'blog' | 'inthenews' {
    return c === 'blog' || c === 'inthenews';
}

When it happens

Trigger: A request to `/uw/gix/news/:category` where `:category` is not `blog` or `inthenews`. Since the parameter is required (not optional), omitting it entirely results in a route-not-found rather than this error. Only a present-but-invalid value triggers this throw.

Common situations: Using a category name from a different news route, guessing a category like `events` or `press`, or a case mismatch (e.g. `Blog` instead of `blog`).
