Remove Paragraph Error

I am having a hard time. I have a document, which is a series of Paragraphs and Tables. Sometimes, I need to remove the last paragraph of the document and I would like to do so without leaving any empty whitespace.

Currently, I am getting this error:

Can't remove the last paragraph in a document section.

Does anyone know why this is happening? Is there a workaround?

Super late to the party, but it doesn't look like this issue is resolved yet. I used the clear and merge functions to remove any whitespace only paragraphs at the end.

var paragraphs = DocumentApp.getActiveDocument().getBody().getParagraphs();
for (var i=paragraphs.length-1; i>=0; i--){
      var line = paragraphs[i];   
      if (line.getText().trim() ) {
        break;
      }
      else {
        line.clear();
        line.merge();
      }
    }

Try this approach, it seems to work as expected, at least I didn't succeed to make it fail ;-)

function deleteAllParagraphs() {
  var doc = DocumentApp.getActiveDocument().getBody();
  doc.insertParagraph(0, '');// insert a dummy paragraph at the beginning of the doc that we are going to let there
  doc.appendParagraph('');// append another dummy in case doc is empty
  for(var p=doc.getNumChildren();p>=0;p--){
    try{
      doc.getChild(p).removeFromParent();
    }catch(e){}
  }
}

EDIT : from the issue tracker I found a better code suggested by #11 cyberaxe that I slightly modified :

function emptyDocument() {
  var document = DocumentApp.getActiveDocument();
  var body = document.getBody();
  body.appendParagraph('');// to be sure to delete the last paragraph in case it doesn't end with a cr/lf
  while (body.getNumChildren() > 1) body.removeChild( body.getChild( 0 ) );
}
