Operation returned an invalid status code 'Unauthorized'

[Anonymous]

When testing an embedded app in Power BI, I am able to get it working with "ServicePrincipal" authentication type, but when I use "MasterUser" authentication type, I get the following error message. What do I need to do to fix this?

I figured out the solution myself. I had to add "Content.Create" API permission to the application registered in AAD.
