Error saying - trying to assign value of type 'Node3D' to a variable of type

Question

I'm new to Godot/ coding in general and been working on hooking animations to movement from a tutorial I was following but I can't open the scene and it just shows the text shown in the image below with no actual errors in the errors tab, not sure if i'm missing something clear or not but any help would be great! :)

Your SophiaSkin node doesn’t have a script so it isn’t using your custom type.
