I created a small application using JavaScript API 4.2 (3D) which works fine.  Now, I am trying to replicate the same within WAB.  However, I have a problem executing sceneView.hitTest() function.  it gave me an "Uncaught TypeError".  I am new to WAB so I can't figure out what I am doing wrong.  I would greatly appreciate any inputs.  


Here is the error I am getting and code. 


onOpen: function(){ 
   this.sceneView.on("click", function(event){ 
        var screenPoint = {x: event.x, y: event.y};        

Thank you,
