Invalid lang

Error message

Invalid lang

What it means

Thrown by the engadget home route when the resolved `lang` is not in the allowLang set {chinese, cn, us, japanese, www}. Note 'us' is internally remapped to 'www', but any other value (e.g. 'uk', 'de', 'fr') is rejected.

Solutions

1. Use one of: chinese, cn, us, japanese (or omit for the cn default).
2. Do not request unsupported locales; Engadget only publishes those variants.

Example fix

// before
/engadget/usa
// after
/engadget/us

const allowLang = new Set(['chinese','cn','us','japanese','www']);
if (!allowLang.has(lang)) throw new Error('Invalid lang');

const isAllowedLang = (l: unknown): boolean =>
  typeof l === 'string' && allowLang.has(l);

When it happens

Trigger: Request to /engadget/:lang with a lang not in the allowLang set.

Common situations: User requests a regional variant Engadget does not actually publish via RSS; typo; passing 'usa' instead of 'us'.
