firebase orderByChild Isnt Working, I have checked alot of posts and nothing is working - Javascript [duplicate]

Question

Here Is My Main Code:

function show_users_posts() {
  document.getElementById('post-spinner').style.display= "none"
    var timestampfinal

    const database = firebase.database()
    database.ref('Cloud/Accounts/' + myParam + '/Posts')
      .orderByChild('sortDate')
      .limitToLast(10) // get 10 most recent entries
      .once('value', function (snapshot) { // <-- consider Promise API instead
        const sortedChildren = [];
        snapshot.forEach(childSnapshot => { sortedChildren.unshift(childSnapshot) }); // reverses the order

        sortedChildren.forEach(childSnapshot => {
          const childKey = childSnapshot.key;
          const childData = childSnapshot.val();

          /* rest of the code */

          var description = childData.Description
          var image = childData.Thumbnail
          var link = childData.Link
          var seconds = childData.Seconds
          var created = parseInt(seconds)
          // The time now
          var now = new Date().getTime();

          // The difference between now and created
          var howLongAgo = created - now;

          // Convert to a positive integer
          var time = Math.abs(howLongAgo);

          // Define humanTime and units
          var humanTime, units;

          // If there are years
          if (time > (1000 * 60 * 60 * 24 * 365)) {
            humanTime = parseInt(time / (1000 * 60 * 60 * 24 * 365), 10);
            units = 'years';
            timestampfinal = humanTime + ' ' + units + ' ago'
          }

          // If there are months
          else if (time > (1000 * 60 * 60 * 24 * 30)) {
            humanTime = parseInt(time / (1000 * 60 * 60 * 24 * 30), 10);
            units = 'months';
            timestampfinal = humanTime + ' ' + units + ' ago'
          }

          // If there are weeks
          else if (time > (1000 * 60 * 60 * 24 * 7)) {
            humanTime = parseInt(time / (1000 * 60 * 60 * 24 * 7), 10);
            units = 'weeks';
            timestampfinal = humanTime + ' ' + units + ' ago'
          }

          // If there are days
          else if (time > (1000 * 60 * 60 * 24)) {
            humanTime = parseInt(time / (1000 * 60 * 60 * 24), 10);
            units = 'days';
            timestampfinal = humanTime + ' ' + units + ' ago'
          }

          // If there are hours
          else if (time > (1000 * 60 * 60)) {
            humanTime = parseInt(time / (1000 * 60 * 60), 10);
            units = 'hours';
            timestampfinal = humanTime + ' ' + units + ' ago'
          }

          // If there are minutes
          else if (time > (1000 * 60)) {
            humanTime = parseInt(time / (1000 * 60), 10);
            units = 'minutes';
            timestampfinal = humanTime + ' ' + units + ' ago'
          }

          // Otherwise, use seconds
          else {
            humanTime = parseInt(time / (1000), 10);
            units = 'seconds';
            timestampfinal = humanTime + ' ' + units + ' ago'
          }

          console.log(timestampfinal)
          
          //childKey
          //childData.FirstName
      

          var html = `<div class="col">`;
          html += `<div class="card h-100">`;
          if (image == "") {
            html += `<img height="300px" width="150px" src="img/No-Image-Placeholder.svg.png" class="card-img-top" alt="...">`;
          }
          else {
            html += `<img src="${image}" class="card-img-top" alt="...">`;
          }
          
          html += `<div class="card-body">`;
          if (verificationstatusforuser == "Verified") {
            html += `<h4 class="card-title">${myParam}<i class="material-icons" style="color: #458eff">verified</i></h5>`;
          }
          else if (verificationstatusforuser == "Owner") {
            html += `<h4 class="card-title">${myParam}<i class="material-icons" style="color: #458eff">verified_user</i></h5>`;
          }
          else if (verificationstatusforuser == "Domain") {
            html += `<h4 class="card-title">${myParam}<i class="material-icons" style="color: #458eff">domain</i></h5>`;
          }
          else if (verificationstatusforuser = "False") {
            html += `<h4 class="card-title">${myParam}</h5>`;
          }
          
          html += `<p class="card-text">${description}</p>`;
          if (link == "") {
            
          }
          else {
            html += `<a href="${link}" target="_blank" type="button" class="btn btn-dark">Open Attached Link</a>`;
          }
          
          html += `</div>`;
          html += `<div class="card-footer">`;
          html += `<small class="text-muted">${timestampfinal}</small>`;
          html += `</div>`;
          html += `</div>`;
          html += `</div>`;
          
          document.getElementById('post-section').innerHTML += html;
        })
      });
    
    
}
        //And The Code Continues, But This is the main part i wanna fix

Here is my Firebase Data Tree:

"Cloud": {
    "Accounts": {
        "User1": {
            "Posts": {
                "1-31-2022-1643620733159": {
                    "sortDate": 1643620733159,
                }
                "1-31-2022-1643620742152": {
                    "sortDate": 1643620742152,
                }
            }
        }
    }
}

Now All I Want To Do is reverse the order making the most recent posts on top and the oldest on bottom, but the code im using doesnt even change the order, and i dont know why, iv tried order by Key, Iv tried everything, nothing is working, The Reference Is Correct Because It Loads All My Posts But Not In The Right Order

Edited Code - adding the log to console:

var database = firebase.database()
    database.ref('Cloud/Accounts/' + myParam + '/Posts').orderByChild('sortDate').once('value', function (snapshot) {
    
      snapshot.forEach(function(childSnapshot) {
        var childKey = childSnapshot.key;
        var childData = childSnapshot.val();
        console.log(childData.sortDate);

Logs This:

1643620733159

1643620742152

It Logs Each Value, But I Need It The Other Way Around.
