Anyone with idea why I get not found ?

 var rightElement = document.getElementById(rightUUID);
 var leftElement = document.getElementById(leftUUID);
 alert(leftElement);//--> [ObjectHTMLSpanElement]

 var range = document.createRange();
 range.setStartAfter(leftElement); 
 range.setEndBefore(rightElement); 
 var sel = window.getSelection();
 sel.removeAllRanges();
 sel.addRange(range);

 document.body.removeChild(rightElement);//-->No error
 document.body.removeChild(leftElement);//-->NotFoundError: Node was not found
