Match media returns error

[woven bronze]

function getLocale(request: NextRequest): string | undefined {
  // Negotiator expects plain object so we need to transform headers
  const negotiatorHeaders: Record<string, string> = {};
  request.headers.forEach((value, key) => (negotiatorHeaders[key] = value));
  // Use negotiator and intl-localematcher to get best locale
  let languages = new Negotiator({ headers: negotiatorHeaders }).languages();
  try {
    return matchLocale(languages, locales, 'pl');
  } catch {
    return 'pl';
  }
}

throws error on edge

Hi @woven bronze. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Hmm, I don't know enough to give you a confident answer yet. However, you can refer to the Next.js documentation on internationalization for more information on handling locales: Next.js Internationalization (https://nextjs.org/docs/pages/building-your-application/routing/internationalization).

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:
