why when I upload file in codeigniter, it says the temporary folder is missing?

why when I upload file in codeigniter, the output it says the temporary folder is missing?

I have already chmod the folder to 777. The source code as shown below. Thank you for the help.

The following is the jquery code the script.

Code:

$(document).ready(function(){
            $('#saveDokumenPelanForm').on('submit', function(e){
                e.preventDefault();
                if($('#dokumenPelan').val() == '')
                {
                    alert("Please Select the File");
                }
                else
                {
                    $.ajax({
                        url: BlankonApp.handleBaseURL() + '/InputPembangunan/ajax_upload',
                       
                        method:"POST",
                        data:new FormData(this),
                        contentType: false,
                        cache: false,
                        processData:false,
                        success:function(data)
                        {
                            $('#uploaded_image').html(data);
                        }
                    });
                }
                return false;
            });
        });

Code:

<div class="modal fade" id="addDokumenPelan" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog modal-lg" role="document">
  <div class="modal-content">
    <form id="saveDokumenPelanForm" method="post" enctype="multipart/form-data">
      <div class="modal-header">
      <h5 class="modal-title" id="exampleModalLabel">Simpan Fail Pelan Kunci dan Lokasi Tapak</h5>
      <button type="button" class="close" data-dismiss="modal" aria-label="Close">
        <span aria-hidden="true">&times;</span>
      </button>
      </div>
      <div class="modal-body">                      
        <div class="form-group row">
          <label class="col-md-2 col-form-label">Muat Naik Fail</label>
          <div class="col-md-10">
            <input type="file" name="dokumenPelan" id="dokumenPelan" class="form-control" required>
            <input type="hidden" id="dokumenPelanInputId"  name="dokumenPelanInputId" class="form-control " value="{$input_id}">
            <input type="hidden" id="dokumenPelanId"  name="dokumenPelanId" class="form-control " value="">
          </div>
        </div>
      </div>
      <div class="modal-footer">
      <button type="button" class="btn btn-secondary" data-dismiss="modal">Tutup</button>
      <button type="submit" class="btn btn-primary" id="btnSaveDokumenPelan">Muat Naik Fail</button>
      </div>
    </form>
  </div>
  </div>
</div>

Code:

function ajax_upload()
{
    if(isset($_FILES["dokumenPelan"]["name"]))
    {
        $config['upload_path'] = './upload/';
        $config['allowed_types'] = 'jpg|jpeg|png|gif';
        $this->load->library('upload', $config);
        if(!$this->upload->do_upload('dokumenPelan'))
        {
            echo $this->upload->display_errors();
        }
        else
        {
            $data = $this->upload->data();
            echo 'Name : '.$data["file_name"];
        }
    }
}

You can check to see where your temp directory is using this php method.

PHP Code:

$tempDir = sys_get_temp_dir()
