Why is my Input Key press not working in Blueprint?

i tried doing all of the above and I can’t seem to get any input on a pawn. I can trigger inputs from the PlayerController Blueprint I’m using by default but by putting an input like mouse wheel for example, isn’t being called in the Character Blueprint I’m using.

I built my project via Top Down Blueprint Template but my Character was created from scratch. So my PlayerController is the default controller that comes with the Top Down Template

Am I missing something?
