Should I use enctype="application/x-www-form-urlencoded" or enctype='multipart/form-data' for sending both upload files and text using AJAX in nodejs?

Question

This is the form html code. I am using enctype="application/x-www-form-urlencoded" currently.

  <form  name="{{this.status}}" class="commonForm" enctype="application/x-www-form-urlencoded" action="/api/upload/{{this.commonID}}" method="post">
<td>
      <input type="file" id="{{this._id}}" class="form-control" name="FileUploadForClient" multiple required {{this.statusDisabled}} />
    </td>
    <td>
      <button type="submit" class="btn btn-primary btn-block col-sm-2" style="font-size:16px" {{this.statusDisabled}}>Submit</button>
</td>
</form>

MY AJAX call:

 var formData = new FormData(this);
    formData.append('text',"Awesome Font!");

    $.ajax({
        type: "POST",
        url: $(this).attr('action'),
        data: formData,
        processData: false,
        contentType: false,
        dataType: "json",
        success: function(response){
            if (response.status == '200') {

        $.LoadingOverlay("hide");

        swal({
        title: "Excellent!",
        text: "Files submitted successfully!",
        icon: "success",
        button: "Ok",
        showCancelButton: true
      }).then((result) => {
        if (result) {
            window.location.reload();
        }
      });

I want to send the text field which I have appended above along with the files uploaded. Files are submitted successfully but when i try to use req.body.text in nodejs it gives undefined. WHy?????????????

Here is the route code:

router.post('/api/upload/:cid',function(req,res,next){
console.log("yes it came under api");

console.log("req.body.text = " + req.body.text + req.query.text);

      upload2(req,res,function(err) {
          if(err) {
            console.log("Error is important = "+ err);
          }
          else
          {
            console.log("Uploaded");

}
})
})

So my main problem is: How to access the text field on server side in nodejs after sending via AJAX with FormData??? Pls help!!!
