Hello, I’ve been having trouble with the “Accessed none trying to read property” error message.
Images of code below.

Essentially I am trying to use line tracing to highlight objects that can be interacted with, and when running it works as I want it to perfectly fine. When I finish simulation however, I get this error code:

I think my understanding is that it’s because a variable is blank (“CurrentTarget”, and Unreal is trying to read something with no value. Advice I’ve read said to try using the validate, but I tried it and it won’t highlight objects anymore if I do.

This node below is the issue.

It works! Don’t know why I didn’t think of using another function, think by the end of Friday my brain was mush haha. Thank you so much.
