thats my BP. i had to create a hit actor ref, so i can know, what to pickup and so on
You’re putting ‘self’ in as the hit actor on one of those calls.
In fact, you don’t need the hitactor ref parameter, because the target param is there for you 
so the is valid and his brench is completely useless?
I think if you disconnect this
it will work?
when i disconnect this, my interaction fails completly.
Ok, sorry
All you need is
line trace → get actor → call interface on it
