Microsoft Power BI Embedded Playground - Error

[Appa1123]

Hi

When testing Microsoft Power BI Embedded Playground

https://microsoft.github.io/PowerBI-JavaScript/demo/v2-demo/index.html#

Specifically the embedded Q&A, when I ran the demo as is without changing any of the keys, I get an error "This content isn't available." this happens only on the Q&A.

Does someone knows if this should work and if it does why do I get the error

See the screenshot

Thanks
