Result

Access to fetch at 'https://www.infragistics.com/angular-apis/webapi/streamHub/negotiate?negotiateVersion=1' from origin 'https://bnmioyogr.github.stackblitz.io' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
