Access to fetch at 'https://developer.microsoft.com/graph' (redirected from 'https://graph.microsoft.com/') from origin 'http://localhost:3000' 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.

@rexkenley I'm not able to reproduce this. Would you mind sharing your app configuration and a code snippet where you are calling the Graph API? Curious why your request is going to https://developer.microsoft.com/graph

@derisen , is this what you need?

authConfig.js

graph.js

[derisen]

@rexkenley thanks! so it looks to me that you are not calling the right Graph API endpoint. In authConfig.js line 64, graphMeEndpoint should have the value https://graph.microsoft.com/v1.0/me. More on the /me endpoint here

@derisen Thank you very much. That was it.
