Error message

Unsupported game: ${game}. Supported games: ${Object.keys(GAME_NAMES).join(', ')}

What it means

Thrown by supercell/blog.ts:198 via `throw new Error(...)` (note: NOT an InvalidParameterError — inconsistent with RSSHub conventions, so it will not be mapped to a clean HTTP 400) when Object.hasOwn(GAME_NAMES, game) is false. GAME_NAMES (line 59) has exactly five keys: clashroyale, brawlstars, clashofclans, boombeach, hayday. The check runs at the very top of the handler, before any network request, so it fails fast.

Solutions

1. Use one of the documented slugs: clashroyale, brawlstars, clashofclans, boombeach, hayday (lowercase, no separators).
2. If you need a newer Supercell title, open an issue or PR adding it to the GAME_NAMES map (and ideally convert the throw to InvalidParameterError while there).

Example fix

// before
GET /supercell/squadbusters/blog
// after
GET /supercell/clashroyale/blog

const SUPPORTED_GAMES = ['clashroyale', 'brawlstars', 'clashofclans', 'boombeach', 'hayday'] as const;

function isSupportedGame(game: string): boolean {
  return (SUPPORTED_GAMES as readonly string[]).includes(game);
}

// usage
if (!isSupportedGame(game)) {
  // reject early with the documented list
}

const GAME_NAMES = {
  clashroyale: 'Clash Royale',
  brawlstars: 'Brawl Stars',
  clashofclans: 'Clash of Clans',
  boombeach: 'Boom Beach',
  hayday: 'Hay Day',
} as const;

type SupportedGame = keyof typeof GAME_NAMES;

function isSupportedGame(game: string): game is SupportedGame {
  return Object.hasOwn(GAME_NAMES, game);
}

When it happens

Trigger: /supercell/<game>/blog[/<locale>] with a game slug outside the five supported: e.g. 'squadbusters', 'moco', a display name like 'Clash Royale', or a typo such as 'clash-royale'.

Common situations: Supercell ships a new title (e.g. Squad Busters) that the route has not been updated to support; the user guesses a slug; the user uses the human-readable game name instead of the slug.
