I just upgraded to `6.0` and `TypeError: Insufficient number of arguments.`

v8::Local<v8::Value> val,
                     Browser::UserTask* out) {
    mate::Dictionary dict;
    if (!ConvertFromV8(isolate, val, &dict))
      return false;
    if (!dict.Get("program", &(out->program)) ||
        !dict.Get("title", &(out->title)))
      return false;
    if (dict.Get("iconPath", &(out->icon_path)) &&
        !dict.Get("iconIndex", &(out->icon_index)))
      return false;
    dict.Get("arguments", &(out->arguments));
    dict.Get("description", &(out->description));
    dict.Get("workingDirectory", &(out->working_dir));
    return true;
  }
};
