Vector3's don't work with the wearedevs c++ api

I came across this problem when i tried teleporting my character with these lines

SendLuaScript("game.Players.LocalPlayer.Character.Head.CFrame += Vector3.new(0,10,0)");
SendLuaScript("game.Players.LocalPlayer.Character.Head.Position += Vector3.new(0,10,0)");
SendLuaScript("game.Players.LocalPlayer.Character:MoveTo(Vector3.new(10,10,10))");

For some reason the first 2 don't work saying "=" expected near "+" and the last one doesn't say anything in the console but doesn't work

Using typeof on Vector3.new(1,2,3) returns "number" instead of Vector3 and prints the last number of the vector which is weird aswell

Can anybody explain why this is or how to fix it?
