  var bidang = e.values[3];
  
  var file = DriveApp.getFileById('------');
  
  var doc = DocumentApp.openById(file.getId()); 
  
  var body = doc.getBody();

  function sendLineNotify(messageNama, messageBidang) {

    var token = ["------"];
    var options = {
        "method": "post",
        "payload": messageNama + " telah mendaftar di Bidang " + messageBidang,

          var ukur = table.getNumRows();    
          ukur -= 3;
          tr.appendTableCell(ukur+1);

Solved the problem, I just forgot the "message=" on payload

"payload": "message=" + messageNama + " telah mendaftar di Bidang " + messageBidang,
