Clamp Camera Rotation isn't working

Hi!

So, I’m trying to clamp the value of rotation in unreal.

I did 2 differents things, the first is very complex, abut work with a controller but not with a mouse for some reason…
The Second,is very simple but don’t work, but i totally don’t get why…

I would like to fix the Second solution :

So basically, I don’t get why the “setWorldRotation” don’t work… It should be clamped beetwen the min value and the max value i set… (like - 100 100 or stuff like that). But it doesn’t .

WHy?

I tried more way… still not working :
