Below is my server.js file.I read documentation of connect-mongo and tried all but did not resolve my issue. I use mongodb compass and removed the connection code because they don't allowed me to insert extra code. Please help me

const app = express();
const MongoDbStore = require("connect-mongo");

// Session config

app.use(
  session({
    secret: process.env.COOKIE_SECRET,
    resave: false,
    store: MongoDbStore.create({
      mongoUrl: process.env.MONGO_CONNECTION_URL,
    }),
    saveUninitialized: false,
    cookie: { maxAge: 1000 * 60 * 60 * 24 },
  })
);```



**Here is the error which I am facing**.

Try to add an collectionName to your MongoStore object:

const session = require("express-session");
const MongoStore = require("connect-mongo").default;

//session configuration
const mongoStore = MongoStore.create({
  mongoUrl: url,
  collectionName: "sessions",
});
app.use(
  session({
    secret: process.env.COOKIE_SECRET,
    resave: false,
    saveUninitialized: false,
    store: mongoStore,
    cookie: { maxAge: 1000 * 60 * 60 * 24 }, //cookie valid for 24 hours
  })
);
where url is "mongodb://localhost/pizza"
