react显示奇怪的数组/对象proptype错误

Question

当我这样做时

AdminDashboard.propTypes = {
  users: PropTypes.object.isRequired
};

我从反应中得到了这个警告

Warning: Failed prop type: Invalid prop users of type array supplied to AdminDashboard, expected object.

然后我改为

AdminDashboard.propTypes = {
  users: PropTypes.array.isRequired
};

我得到了这个

Warning: Failed prop type: Invalid prop `users` of type `object` supplied to `AdminDashboard`, expected `array`.

你想要什么，做出反应？

更新：

我的用户看起来像这样

    "university": "Havard",
