Txt File Upload With PHP-CodePudding

For some reason the following code keeps returning the "Unknown Error Type" found in the script. I have used similar code for both image and video file types and it worked fine, not sure what is wrong with this one. On the image and video scripts I did not receive the unknown error once. I have also made sure the folder that I am uploading to has the proper permissions.

HTML:

<?php
include "documentsconfig.php";

if(!isset($_SESSION['uname'])){
    header('Location: http://ts558.cloud/index.php');
}
?>
<?php
  if ($handle = opendir('allDocs')) {
    while (false !== ($file = readdir($handle))) {
      if ($file != "." && $file != "..") {
        $thelist .= '<li><a download href="allDocs/'.$file.'">'.$file.'</a></li>';
      }
    }
    closedir($handle);
  }
?>
