Getting this error when trying to `applyEffect` free distort

var effectString =
          '<LiveEffect name="Adobe FreeDistort"><Dict data="DistortTopLeftX 0 DistortTopLeftY 0 DistortTopRightX 50 DistortTopRightY -20  DistortBottomLeftX -10 DistortBottomLeftY 70 DistortBottomRightX 60 DistortBottomRightY 50"/></LiveEffect>';
        item.applyEffect(effectString);

The problem seems to be caused by the application of the live effect, as the code worked with a simple effect applied, and I'm applying it to a simple PathItem.

While searching it seems like the error is a vague one, so any help would be appreciated

• The name and number of arguments for Free Distort were incorrect
• I expect the number you intended to use is the scale factor, although a percentage will also work

  var sel = doc.selection ;

  var topLeft = [0, 0] ;

  var targetItem = sel[0] ;
  targetItem.applyEffect(effectString) ;
