本机嵌入在mongoose中的自动重新连接功能在我的项目上不起作用。

我实际上收到了一个错误返回，但是在我配置的X秒之后它不会再次启动。

除了凭据是否正确之外，我希望mongoose尝试每X秒登录一次（因此每次都向我发送一个日志），但实际情况并非如此

下面是有问题的文档:https://mongoosejs.com/docs/connections.html#options

下面是我的代码:

import mongoose from "mongoose"

const options = {
    dbName: "testbdd",
    pass: "qwe",
    user: "alex",
    useNewUrlParser: true,
    serverSelectionTimeoutMS: 1000,
    heartbeatFrequencyMS: 1000,
    useUnifiedTopology: true
}
const uri = `mongodb://localhost/`



mongoose.connection.on('disconnected', function () {
    console.log('Mongo db disconnected!');
});

mongoose.connect(uri, options).then(() => {
    console.log('First Mongo db connexion success !')
}).catch((error) => {
    console.log('First Mongo db connexion fail !')
    console.log(error)
})

下面是我运行节点服务器时的返回结果:

backend_1  | }

这些选择应该很有效，不是吗？

serverSelectionTimeoutMS: 1000,
heartbeatFrequencyMS: 1000,
useUnifiedTopology: true

我真的迷路了。我怀疑这是猫鼬代码没有工作，这必然是我的实现。

你能帮我吗？
