HTTP/3xx (Redirection)

300 Multiple Choices

The request has more than one possible response and the client should choose one of them.

❓ Why does this happen?

Content negotiation offered several representations (languages, formats) without a preferred default.

✅ How to fix it

Send explicit Accept / Accept-Language headers or follow the preferred Location header if present.

Return or handle 300 in your stack

// app/api/resource/route.ts
export function GET() {
  return Response.json(
    { error: "Multiple Choices", status: 300 },
    {
      status: 300
    }
  );
}
