Solutions

1. Use one of the documented keys: `/ithome/it`, `/ithome/soft`, `/ithome/win10`, `/ithome/win11`, `/ithome/iphone`, `/ithome/ipad`, `/ithome/android`, `/ithome/digi`, `/ithome/next`.
2. If a new category is needed, add it to the `config` map in lib/routes/ithome/index.ts with its URL builder.

Example fix

// before: /ithome/news
// after:  /ithome/it

const cfg = config[ctx.req.param('caty')];
if (!cfg) throw new InvalidParameterError(`Bad category. Valid: ${Object.keys(config).join(', ')}`);

const isKnownCategory = (c: string): c is keyof typeof config => c in config;

When it happens

Trigger: Request to `/ithome/:caty` with a category not in the config map — e.g. `/ithome/news`, `/ithome/hardware`, a typo, or a Chinese display name instead of the English key.

Common situations: User passes the Chinese display name instead of the English key; outdated docs referencing a removed category; typo.
