为啥在cloudflare worker中代理gemini api报错User location is not supported for the API use.

为啥在cloudflare worker中代理gemini api报错User location is not supported for the API use. 

这个怎么解决？

这是我的worker代码：

addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request));
})

async function fetchAndApply(request) {
  if (request.method === 'OPTIONS') {
    // 对于预检请求，设置允许的请求方法、请求头和响应头
    return new Response(null, {
      headers: {
        'Access-Control-Allow-Origin': '*', // 允许的域名，可以设置具体的域名
        'Access-Control-Allow-Methods': '*', // 允许的请求方法
        'Access-Control-Allow-Headers': '*' // 允许的请求头，例如 Content-Type 和 Authorization
      }
    })
  }
  //const apiKey = request.headers.get("apikey");
  // if ("33453535433" !== apiKey) {
  //return new Response("404 Not Found", { status: 404 });
  //}
  let response = null;
  let method = request.method;
  let request_headers = request.headers;



  let url = new URL(request.url);
  let url_hostname = url.hostname;
  url.protocol = 'https:';
  url.host = 'generativelanguage.googleapis.com';

  //https://generativelanguage.googleapis.com/v1beta/models/gemini-pro:generateContent?key=${googleApiKey}

  let new_request_headers = new Headers(request_headers);
  new_request_headers.set('Host', url.host);
  new_request_headers.set('Referer', url.protocol + '//' + url_hostname);

  let original_response = await fetch(url.href, {
    method: method,
    headers: new_request_headers,
    body: request.body
  })


  let original_response_clone = original_response.clone();
  let original_text = null;
  let response_headers = original_response.headers;
  let new_response_headers = new Headers(response_headers);
  let status = original_response.status;

  new_response_headers.set('Cache-Control', 'no-store');
  new_response_headers.set('access-control-allow-origin', '*');
  new_response_headers.set('access-control-allow-credentials', true);
  new_response_headers.delete('content-security-policy');
  new_response_headers.delete('content-security-policy-report-only');
  new_response_headers.delete('clear-site-data');

  original_text = original_response_clone.body
  response = new Response(original_text, {
    status,
    headers: new_response_headers
  })

  return response

}
