Power BI Embed Dashboard - no data shown: CORS Error for subscribe

Hi,

I have an error Embedding Power BI dashboard. The tiles show up but the data is not.

It has a CORS Error.

I am not sure why the error info says TokenExpired when the app has just started.

Any ideas?

Are you sure it is a CORS error? From looking at the error info you posted, my guess is that you are using an access token that is over 60 minutes old which has expired. How often are you refreshing the access token?
