Invalid tab: ${tab}

Error message

Invalid tab: ${tab}

What it means

Thrown by the Voronoi popular route handler when the `tab` path parameter, after lowercasing, is not a key in `TabMap` (`most-popular`, `most-discussed`, `most-viewed`). This is the route-level guard (line 34) that runs before calling `getPostItems`. It uses `Object.hasOwn(TabMap, tab.toLowerCase())`. This is a generic `Error`.

Solutions

1. Use one of the lowercase tab keys: `most-popular`, `most-discussed`, or `most-viewed`.
2. Omit the tab parameter to default to `most-popular`.
3. Check the TabParam description table for valid values.

Example fix

// before
GET /voronoiapp/popular/trending
// after
GET /voronoiapp/popular/most-popular

if (!Object.hasOwn(TabMap, tab.toLowerCase())) {
    throw new InvalidParameterError(
        `Invalid tab: ${tab}. Valid: ${Object.keys(TabMap).join(', ')}`
    );
}

function isValidPopularTab(tab: string): tab is 'most-popular' | 'most-discussed' | 'most-viewed' {
    return Object.hasOwn(TabMap, tab.toLowerCase());
}

When it happens

Trigger: A request to `/voronoiapp/popular/:tab` where `:tab` is not `most-popular`, `most-discussed`, or `most-viewed`. The parameter defaults to `most-popular`, so omitting it is safe. Only an explicit invalid value triggers the error.

Common situations: User guesses a tab name like `top` or `trending`, or uses the uppercase API value `POPULAR` instead of the lowercase path key `most-popular`.
