Hi,
I'm creating a conection in Power BI Embedded in Javascript, but not I can, the error:
Failed to load https://login.microsoftonline.com/common/oauth2/token: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:13526' is therefore not allowed access.
Thanks
