FPointDamageEvent error "incomplete type is not allowed" (Unreal Engine 5.1)

Question

The instructor in the C++ course I'm following used this code here, and I copied it exactly: Code the course instructor used

But I get this error. Not sure what to do. I know that the instructor is doing this in 4.27 and I'm doing it in 5.1. Did something change between those two versions that may have caused this error? How to I get around it? The error I'm receiving

Here's my whole function for reference: Whole function

I also faced this problem. Here is the workaround. For UE5.1 you need to write this in your file, #include "Engine/DamageEvents.h".
