What should I do if I see a CORS error in the console?

A CORS (Cross-Origin Resource Sharing) error indicates that your JavaScript code is trying to access a resource from a different domain than the one the script is running on, and the server isn't allowing that access. To fix a CORS error, the server providing the resource needs to be configured to allow cross-origin requests from your domain. This typically involves setting appropriate HTTP headers like `Access-Control-Allow-Origin`. Alternatively, you might be able to use a proxy server on your own domain to fetch the resource.
