Node.js 会话未使用express会话和connect会话续集持久化

我正在使用Sequilize库连接MySql数据库。一切正常。但是，每次重新加载浏览器时，会话都不会持久化。一个新的会话将以null userId存储在数据库中，有时甚至不止一个。我不知道为什么。我正在从express服务器上为我的VUESPA服务，它工作得非常好

我研究了StackOverflow，一些解决方案指向cors，但我只为VUE和Node使用一个端口，所以应该没有问题。我们将非常感谢您的帮助

下面是代码以及一些显示会话数据库中的行的图像

这是应用程序初始化的代码。 这是app.js文件的代码

我认为这是登录功能中的一个问题
