Invalid language: . Allowed values are

Error message

Invalid language: ${language}. Allowed values are: ${[...validLanguages].join(', ')}

What it means

Thrown by the bandisoft history route when the :language path parameter is not one of the values in languageOptions (en, cn, tw, jp, ru, es, fr, de, it, sk, uk, be, da, pl, br, cs, nl, sl, tr, th, gr, uz, ro, kr). The whitelist is built from languageOptions and the error enumerates every accepted code.

Solutions

1. Pick a code from the error message's allowed list (these map 1:1 to {lang}.bandisoft.com subdomains).
2. When adding a locale, append it to languageOptions so validation, the example, and the subdomain construction stay in sync.

const VALID_LANGS = new Set(languageOptions.map((o) => o.value));
if (!VALID_LANGS.has(language)) {
    throw new InvalidParameterError(`Invalid language: ${language}. Allowed: ${[...VALID_LANGS].join(', ')}`);
}

function isBandisoftLanguage(v: string): boolean {
    return languageOptions.some((o) => o.value === v);
}

When it happens

Trigger: Calling the route with a language code outside the supported set, e.g. 'pt' instead of 'br', or a two-letter code Bandisoft does not host a subdomain for.

Common situations: User supplies an ISO code Bandisoft doesn't use; case mismatch; doc lists a removed locale.
