// Respond to OPTIONS method
export const onRequestOptions: PagesFunction = async () => {
return new Response(null, {

// Set CORS to all /api responses
export const onRequest: PagesFunction = async (context) => {
const response = await context.next();
response.headers.set("Access-Control-Allow-Origin", "*");
