Unable to get a property from a blueprint actor

[czcz1024]

public static void AppendString(ObjectReference self)
{
Actor blueprintActor = self.ToActor();
string v="";
var r= blueprintActor.GetText("vstr", ref v);
Debug.AddOnScreenMessage(-1, 10.0f, Color.AliceBlue, "get "+r+",v "+v);

}
i have a function like this
i create an actor and add a var named "vstr",and drag it in to sence
and in lev blueprint run Excute Managed Function and pass an actor instance.
but GetText return false

what's wrong?

You are trying to obtain a text property using blueprintActor.GetText() function. The property itself should be set to Text type instead of String.
