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.

OPTIONS https://wabi-west-europe-b-primary-redirect.analysis.windows.net/powerbi/refresh/subscribe

Response: 200

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

Any ideas?
