cloudinary_sdk does not work on CLI or PhpUnit.

For some reason the Cloudinary SDK module is standalone and not part of the Cloudinary module itself. It also only configures itself when a web request is made. This means it breaks on CLI and adds overhead for pages not displaying images from Cloudinary.

See cloudinary_sdk.init_subscriber

  /**
   * {@inheritdoc}
   */
  public static function getSubscribedEvents() {
    return [KernelEvents::REQUEST => ['onEvent', 0]];
  }

  /**
   * Handles event on subscriber.
   */
  public function onEvent($cloudinaryConfig = []) {
    if (!is_array($cloudinaryConfig)) {
      $cloudinaryConfig = cloudinary_sdk_config_load();
    }

    if (!empty($cloudinaryConfig)) {
      \Cloudinary::config($cloudinaryConfig);
      return TRUE;
    }

    return FALSE;
  }
