This code works.

function acf_set_featured_image( $value, $post_id, $field  ){
  $id = $value;
  if( ! is_numeric( $id ) ){
    $data = json_decode( stripcslashes($id), true );
    $id = $data['cropped_image'];
  }
  update_post_meta( $post_id, '_thumbnail_id', $id );
  return $value;
}

// acf/update_value/name={$field_name} - filter for a specific field based on it's name
add_filter( 'acf/update_value/name=fieldname', 'acf_set_featured_image', 10, 3 );
