Accessed none error even though I used isvalid node

Hey, I’m trying to move an actor along a spline as soon as the actor is spawned, but the “set location and rotation” node can’t seem to work, giving off an “Accessed none” error even though I used the isvalid node to check if the actor actually exists before trying to move it.

Do you guys have any idea on what I’m doing wrong? It’s possible that it’s something obvious but I can’t seem to figure out the issue.

I’m really grateful for any input!

In the error it says that SplineRef is the one you should be checking is valid not self, youre accessing Spline through the null SplineRef, hence Accessed None.
