Microsoft Edge Chromium - Headers that contain Access-Control-Allow-Origin are not working

Copper Contributor

I am seeing the following type of error in the browser console indicating that valid CORS requests are being rejected. The same functionality is working in the original Microsoft Edge, Internet Explorer 11, and Google Chrome.

 

Access to XMLHttpRequest at 'https://someplace.domain.net/openam/json/authenticate?realm=/domain/system' from origin 'https://someotherplace.domain.net' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

 

Is there some reason for this to work differently in Edge Chromium than in other browsers? If this is a bug is there a workaround? If it is a "feature" how to we code our requests to avoid it?

 

Thanks for any assistance you can provide...

Are you still seeing this behavior?

No with the latest version that I have (78.0.249.1) the issue no longer occurs.
