No way to avoid ReplicaSetNoPrimary errors

We are also running on Vercel with the mongodb driver and are receiving these errors randomly.

Just for comparison, we are running:

  • Vercel Pro plan

These packages:
“next-auth”: “^4.24.4”,
“mongodb”: “^4.13.0”,
“next”: “^14.1.0”

Does everyone also have next-auth running?
This is my mongodb connection implementation:

import { MongoClient } from "mongodb";

const uri = process.env.MONGODB_URI;
const options = {
    useUnifiedTopology: true,
    useNewUrlParser: true,
};

let mongoClient = null;
let database = null;

if (!process.env.MONGODB_URI) {
  throw new Error('Invalid/Missing environment variable: "MONGODB_URI"')
}

export async function connectToDatabase() {
    try {
        if (mongoClient && database) {
            return { mongoClient, database };
        }
        if (process.env.NODE_ENV === "development") {
            if (!global._mongoClient) {
                mongoClient = await (new MongoClient(uri, options)).connect();
                global._mongoClient = mongoClient;
            } else {
                mongoClient = global._mongoClient;
            }
        } else {
            mongoClient = await (new MongoClient(uri, options)).connect();
        }
        database = await mongoClient.db(process.env.NEXT_ATLAS_DATABASE);
        return { mongoClient, database };
    } catch (e) {
        console.error(e);
    }
}
