Have you setup the Cross origin resource sharing (CORS) policy?

You basically need to add your custom domain from where you are trying to initiate this request as an allowed origin in the CORS policy.

You need to ensure:

  • CORS is set up correctly as mentioned by @harwinder-singh.

  • Pay special attention to allowing the HTTP OPTIONS method, which is the type of method used for preflight operations.

  • Make sure the dispatcher allows CORS headers and does not block the OPTIONS method.
