Code

public function massageFormValues(array $values, array $form, FormStateInterface $form_state) {

  // Since file upload widget now supports uploads of more than one file at a
  // time it always returns an array of fids. We have to translate this to a
  // single fid, as field expects single value.
  $new_values = [];
  foreach ($values as &$value) {
    foreach ($value['fids'] as $fid) {
      $new_value = $value;
      $new_value['target_id'] = $fid;
