Error message

Invalid language

What it means

InvalidParameterError thrown by the Pornhub model handler when the language path segment fails isValidHost. Identical guard to the category_url route: the language is interpolated into https://{language}.pornhub.com/model/... and must be a valid DNS-label subdomain, otherwise the request is rejected before fetching.

Solutions

1. Use a bare lowercase Pornhub language subdomain code such as www, cn, jp, fr, de.
2. Keep the segment free of dots, slashes, spaces, and special characters.
3. Omit language to default to 'www'.
4. Verify the subdomain exists (e.g. https://cn.pornhub.com) before using a code.

Example fix

// before: /pornhub/model/username/www.
// after:  /pornhub/model/username/www

import { isValidHost } from '@/utils/valid-host';
function isValidLanguageSegment(lang: string): boolean {
  return typeof lang === 'string' && lang.length > 0 && isValidHost(lang);
}
if (!isValidLanguageSegment(language)) {
  // reject before building the pornhub model URL
}

const isValidLanguageSegment = (lang: unknown): lang is string =>
  typeof lang === 'string' && /^[\dA-Z](?:[\dA-Z-]{0,61}[\dA-Z])?$/i.test(lang);

try {
  // model handler
} catch (e) {
  if (e instanceof InvalidParameterError && /Invalid language/.test(e.message)) {
    // surface allowed language subdomain codes
  }
}

When it happens

Trigger: Passing a language segment containing dots, slashes, underscores, spaces, special characters, or an empty string; using a full locale identifier instead of a bare subdomain code.

Common situations: User passes 'en-US' style locales; adds a trailing dot or slash; leaves an encoded character; uses a code Pornhub lacks a subdomain for.
