Hi!
I have problem with uploading files using API and JWT token, public and private key.

I have used it a long time and everything was okay, but now I don't receive a response from boxcom, there are an empty body.

  Hello, this is my second account.

  This is my code:

  $json = file_get_contents(ROOT_SITE_DIR.'/data/boxComConfigs/new_box.json');
  $config = json_decode($json);
  
  $private_key = $config->boxAppSettings->appAuth->privateKey;
  $passphrase = $config->boxAppSettings->appAuth->passphrase;
  $key = openssl_pkey_get_private($private_key, $passphrase);
  
  
  $authenticationUrl = 'https://api.box.com/oauth2/token';
  
  $claims = [
      'iss' => $config->boxAppSettings->clientID,
      'sub' => $config->enterpriseID,
      'box_sub_type' => 'enterprise',
      'aud' => $authenticationUrl,
      'jti' => base64_encode(random_bytes(64)),
      'exp' => time() + 45,
      'kid' => $config->boxAppSettings->appAuth->publicKeyID
  ];
  
  
  $assertion = JWT::encode($claims, $key, 'RS512');
  
  
  $params = [
      'grant_type' => 'urn:ietf:params:oauth:grant-type:jwt-bearer',
      'assertion' => $assertion,
      'client_id' => $config->boxAppSettings->clientID,
      'client_secret' => $config->boxAppSettings->clientSecret
  ];
  $client = new Client();
  
  
  
  $response = $client->request('POST', $authenticationUrl, [
      'form_params' => $params
  ]);
  
  
  
  $data = $response->getBody()->getContents();
  $token = json_decode($data)->access_token;
  
  
  //update file
  //$url = "https://upload.box.com/api/2.0/files/807022067600/content";
  
  // upload file
  $url = "https://upload.box.com/api/2.0/files/content";
  
  if (isset($_POST['btnUpload'])) {
  
  
      $file_upload = $_FILES['file']['tmp_name'];
  
  
  
      $json = json_encode(array(
          'name' => $_FILES['file']['name'],
          'parent' => array('id' => 0),
          "shared_link" => array(
                   "access" => "open"
          )
      ));
  
      $filePath = $_FILES['file']['tmp_name'];
      $fileName = $_FILES['file']['name'];
      $fileType = $_FILES['file']['type'];
  
      $fields = array(
          'attributes' => $json,
      );
  
  
  
      try {
          $ch = curl_init();
  
  
          curl_setopt($ch,CURLOPT_URL, $url);
  
  
  
  
          curl_setopt($ch, CURLOPT_HTTPHEADER, array(
              'Authorization: Bearer '.$token,
              'Content-Type: multipart/form-data'
          ));
  
          curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
          curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
  
          $response = curl_exec($ch);
          curl_close($ch);
  
  
      } catch (Exception $e) {
          $response = $e->getMessage();
          print_r($response);
  
      }
