New Error in Looker Fetch Code when importing to GSheet

Hi,

I am heavy user of this script, that I use to import data from Looker to GSheet. The script was working fine until this morning when I got the following errror: “Error on line 5: The markup in the document following the root element must be well-formed. (line 4).” Anyone getting the same error? How can I fix it?

function lookerFetchHtmlTable(url) {

  url = url.replace(/(\/\w+\.)txt(\?)?/, "$1html$2");

  var xmlText = UrlFetchApp.fetch`Preformatted text`(url).getContentText();

  var document = XmlService.parse(xmlText);

  var root = document.getRootElement();

  

  var rows = root.getChildren("tr");

  var header = rows[0];

  var headercells = header.getChildren("th").map(

    function(t) { return t.getValue(); }

  );



  var bodycells = rows.slice(1, rows.length).map(function(el) {

    return el.getChildren("td").map(

      function(t) { 

        var val = t.getValue();

        if(val == ""){return ""};

        var dateMatch = /(\d{4})\-(\d{2})-*(\d{0,})/.exec(val);

        while (dateMatch != null) {

          // first index is full match

            return new Date(dateMatch[1], dateMatch[2] - 1, dateMatch[3] || 1);

        };

        var strMatch = val.match(/[-a-zA-Z]/);

        if (strMatch) {

          return String(val);

        };

    

        val = val.replace(/[^\d]/g, '');

        return Number(parseInt(val));

      }

    );

  });



  var finalArray = [headercells];

  Array.prototype.push.apply(finalArray, bodycells);

  return finalArray;

}
