error quickmongo

Missing the example of the bot with mongodb, I’m trying to use quickmongo to use the mongodb database but I’m finding a problem with the package

in the index I add this in place of the quick.db application

const { Database } = require("quickmongo");
const db = new Database("mongodb+srv://giveaway:[e-mail]/giveaway?retryWrites=true&w=majority");

and I get this error at the terminal

I’ve tested the code just now on my bot and it worked perfectly. Here is the extended GiveawaysManager class:

const { GiveawaysManager } = require("discord-giveaways");
const { Database } = require("quickmongo");
const db = new Database("mongodb://localhost/giveaways");

db.once("ready", async () => {
    if (await db.get("giveaways") === null) await db.set("giveaways", []);
});

class GiveawayManager extends GiveawaysManager {

    async getAllGiveaways() {
        return await db.get("giveaways");
    }

    async saveGiveaway(messageID, giveawayData) {
        await db.push("giveaways", giveawayData);
        return true;
    }

    async editGiveaway(messageID, giveawayData) {
        const giveaways = await db.get("giveaways");
        const newGiveawaysArray = giveaways.filter((giveaway) => giveaway.messageID !== messageID);
        newGiveawaysArray.push(giveawayData);
        await db.set("giveaways", newGiveawaysArray);
        return true;
    }

    async deleteGiveaway(messageID) {
        const data = await db.get("giveaways");
        const newGiveawaysArray = data.filter((giveaway) => giveaway.messageID !== messageID);
        await db.set("giveaways", newGiveawaysArray);
        return true;
    }

}

module.exports = GiveawayManager;
