Why am I getting a CORS error when doing OpenUI5 walkthrough tutorial?

Hi all

I am getting this error while doing the walkthrough tutorial and I would like to know if I can prevent it:

Access to XMLHttpRequest at 'https://sdk.openui5.org/resources/sap/ui/demo/walkthrough/view/App.view.xml' from origin 'http://localhost:8080' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Thanks

Herman

Thanks for the response.

The problem went away and I am not sure why.
