Embedding report with effective identity + RLS - username NULL

Hi,

I have the following issue with Power BI Embedded App Owns Data + service principal + RLS

I have followed all steps in the to-do in terms of registering an azure app, delegating permissions, enabling service principal etc.

I added all the required IDs to the App-Owns-Data visual studio solution web.config

Whenever I launch the solution though I run into various issues.

I am changing my code for RLS in the Models\embedconfig.cs

What I have not solved yet is amending the code for RLS with effective identity.

did not help since my username appears to be NULL and thus it goes to the ELSE clause ("generate embed token for report without effective identity")

Does anyone have an idea what the problem might be?
