Error if print_f($file) or print_f($request) is not in code

[FragginWagon]

Need thoughts on this:

            $request = new \Flow\Request();

    $config = new \Flow\Config();

    $config->setTempDir('./');

    $file = new \Flow\File($config, $request);

    if ($_SERVER['REQUEST_METHOD'] === 'GET') {
        if ($file->checkChunk()) {
            header("HTTP/1.1 200 Ok");
        } else {
            header("HTTP/1.1 204 No Content");
            return ;
        }
    } else {
    //print_r($file); // -> UNCOMMENTING THIS MAKES THIS CALL WORK...
      if ($file->validateChunk()) {
          $file->saveChunk();
      } else {
          // error, invalid chunk upload request, retry
          header("HTTP/1.1 400 Bad Request");
          return ;
      }
    }
    if ($file->validateFile() && $file->save($request->getFileName())) {
        // File upload was completed
    } else {
        // This is not a final chunk, continue to upload
    }

Forgot to mention, this is what the message is and where it fails:

I think you should also check if request method is OPTIONS and return 200 status code if it is.
