Error: no value present

[fringe hill]

Hello, I get the error "no value present" when I try to return a created object with filled attributes.
I did search already for help to this issue, but most of the results are facing the problem of array objects, what doesn't fit here.
When I add more then a Id to my object the error occurs.
Code below.
