Passport.js和MongoStore错误"在MongoStore找不到连接策略"

Question

我在Node.js服务器上收到这个奇怪的错误:

 Error: Connection strategy not found
        at MongoStore (/Users/amills001c/WebstormProjects/lectal_all/manager/node_modules/connect-mongo/src/index.js:100:23)
        at Object.<anonymous> (/Users/amills001c/WebstormProjects/lectal_all/manager/app.js:42:12)
        at Module._compile (module.js:425:26)

我们正在使用Passport和Express.

错误发生在mongoose_connection: mongoose.connection以下代码段中的行:

app.use(expressSession({
    secret: 'foobar',
    cookie: {
        secure: false,
        maxage: 1160000000,
        resave: true,
        saveUninitialized: true
    },
    store: new MongoStore({
        mongoose_connection: mongoose.connection   /*<== error happens here*/
    })
}));

这是什么错误,我该如何解决？

根据文档,我认为该行应该是:

store: new MongoStore({
    mongooseConnection: mongoose.connection
});

用mongooseConnection而不是mongoose_connection.
