# Custom field uuid onCreate Generate and save UUID does not work

I write function to create Item by use Directus SDK createitem , and i got error "Access to fetch at 'https://apiEndpoint/items/Subscriber' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled". even if I follow solution to config cors through https://docs.directus.io/self-hosted/config-options.html#cors, but it not solved.
