CORS policy: No 'Access-Control-Allow-Origin' header is pre…

When trying to access a resource from a different origin, the browser blocked the request due to CORS policy. This is a security feature to prevent unauthorized access to resources.

The server did not include the 'Access-Control-Allow-Origin' header in its response, which is required for cross-origin requests. Without this header, the browser assumes that the resource is not accessible from the requesting origin.

To resolve this, you need to configure the server to include the 'Access-Control-Allow-Origin' header in its response. You can set it to allow specific origins or use a wildcard '*' to allow all origins.
