**Description**  
Hey guys,  
i’m using the sample Project to create and open breakout rooms programmatically.  
Im using my zak to get the correct permissions

I can already create breakout rooms and also assign users to the room.  
I even can open the breakout rooms with the given custom ui from the sample app.  
But when trying to call the startBO() Method programmatically i get get the error ‘BOControllerError\_UPLOAD\_FAIL’, what does the error mean?

Any ideas on how to fix the error?

3. Assign user to BO
4. try to start BO’s
