[Paraview] Open remote file Error via Paraviewweb (Paraview3.98.0)

[Ewin]

Hi all,
     I want to show paraview result on webpage,  and I setup the paraviewweb 
envi (version 3.98.0). 
     Method "paraview.loadData" can get a normal source object and show well, 
but it can only open native file. So, I use "paraview.OpenDataFile" to read the 
remote file, but I got an Error:
 
      'NoneType' object has no attribute 'Representations'‍
     
     My Code:
            paraview = new Paraview(serverUrl);‍
            ......
           var reader = paraview.OpenDataFile(val);‍
           paraview.SetDisplayProperties( {
                'proxy' : reader ‍,
                 'view'  : myview,
                Representation : 'wirefire‍'
            } );‍


Any help will be appreciated！
Thanks all！
