Headers is not defined

[inuoluwadunsimi]

I get a headers is not defined error each time I try to use resend in my nodejs app

I have been using this as a workaround for a while, can a more permanent solution be done please?
import fetch, { Headers, Response, Request } from "node-fetch";

if (!global.fetch) {
global.fetch = fetch as unknown as typeof global.fetch;
global.Headers = Headers as unknown as typeof global.Headers;
global.Response = Response as unknown as typeof global.Response;
global.Request = Request as unknown as typeof global.Request;
}
