Employee List part doesnt load

I have tackled the Challenge in a slightly differnt approach by using forEach instead.

However when i reload my page the employee list part doesn't always work.

My code is:

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
  if(xhr.readyState === 4 && xhr.status === 200) {
    var employees = JSON.parse(xhr.responseText);
    const ulEmp = document.createElement('ul');
    ulEmp.className = "bulleted"
    document.getElementById('employeeList').appendChild(ulEmp);

    employees.forEach((employee) => {             
          const liEmp = document.createElement('li');
          const ulList = document.querySelector('ul'); 
          ulList.appendChild(liEmp);          
          liEmp.className = employee.inoffice ? "in" : "out";
          liEmp.textContent = employee.name;                  
                          });
 } 
 };
xhr.open('GET', '../data/employees.json');
xhr.send();


const xhrRooms = new XMLHttpRequest();
xhrRooms.onreadystatechange = function () {
  if(xhrRooms.readyState === 4 && xhrRooms.status === 200){
          const rooms =JSON.parse(xhrRooms.responseText);
          const ulRoom = document.createElement('ul')                    
          ulRoom.className = "rooms"
          document.getElementById('roomList').appendChild(ulRoom);

          rooms.forEach((roomer) => {
          const liRoom = document.createElement('li');
          document.querySelector('#roomList ul').appendChild(liRoom);
            if(roomer.available === false){
              liRoom.className = "full";
            }else {
              liRoom.className ="empty";
            }
           liRoom.innerHTML = `${roomer.room}`          
          });  
  }};
  xhrRooms.open('GET', '../data/rooms.json');
  xhrRooms.send();

would appreciate any help on why this might be occuring
