File Upload Field not working

I just tried to create a simple mandatory file upload field in a custom form like this:

public function buildForm(array $form, FormStateInterface $form_state) {    $form['#attributes'] = array('enctype' => "multipart/form-data");    $form['pdf_file'] = array(     '#type' => 'file',     '#title' => $this->t('PDF File'),     '#description' => $this->t('PDF files only'),     //'#multiple' => TRUE,     '#required' => TRUE,   );    $form['submit'] = array(     '#type' => 'submit',     '#value' => $this->t('Save'),   );    return $form; }

And that did not work.

When submitting a file (no matter what kind of), i get this error all the time:

“PDF File field is required.”

Does anybody have an idea what I am doing wrong?

I am using Drupal 8.2
