We have an IFS Aurena Webpage set up, and we’re trying to set up a Blazor web applications to handle some of the data. When trying to fetch or call to our IFS Aurena webpage to GET data, we’re met with CORS Policy.
Access to fetch at 'https://ourAurenaPage/something.svc' from origin 'https://webapplication' has been blocked by CORS policy: Request header field authorization is not allowed by Access-Control-Allow-Headers in preflight response.

Yes - we don’t allow CORS calls, and it’s not configurable… you need backend proxied calls from the 2:nd domain, or some sort of proxy in front of IFS Cloud.
