Error connecting to MongoDB: TypeError: Cannot read properties of undefined (reading ‘connect’)

const logger = require(“./logger”);
const { MongoClient, ObjectId } = require(“mongodb”);

let db = null;
let mongouri;
let client;
const connectToDatabase = async () => {
if (db) {
return db;
}

mongouri = process.env.MONGO_URI;
console.log(“mongo uri:”,mongouri);
if (!client) {
try {
client = new MongoClient(mongouri, { useNewUrlParser: true, useUnifiedTopology: true });
} catch (error) {
console.log(“Error with mongo client:”, error.toString());
}
}

try {
await client.connect();
const database = client.db(“cs_db_dev”);
console.log(“Connected to MongoDB”);
} catch (error) {
console.log(“Error connecting to MongoDB:”, error.toString());
}

// logger.debug(“mongo client output check”, { client });
// logger.debug(“Connected to mongodb database”);

const insertMany = async (db, collectionName, data) => {
return db.collection(collectionName).insertMany(data);
};

const upsert = async (db, collectionName, filter, update) => {
return db
.collection(collectionName)
.updateOne(filter, update, { upsert: true });
};

const find = async (db, collectionName, filter) => {
return db.collection(collectionName).find(filter).toArray();

};

const getCollection = (db, collectionName) => db.collection(collectionName);
