touchAction.Perform() using simple MoveTo() gives server error expecting element

See original GitHub issue

Not sure if I’m calling this correctly or not, but performing a simple MoveTo() doesn’t work and results in a server error that expects an Element.

var action = new TouchAction(appSession);
action.MoveTo(100, 100);
action.Perform();

PowerShell output:
