MongoDB Problems while inserting nested data

I try to build a database for a giveaway bot using MongoDB. Once a new giveaway is created the bot runs the following code to write the new giveaway into the databank:

const {mongoose} = require("mongoose")
const mainSchema = require('../models/mainSchema')

module.exports = {
  async execute(interaction){

  await new mainSchema ({
    guild_id: 1234567890,
    giveaways: [{
      identifier: 34,
      destination: 987654321,                      
    }],                                                                        
  }).save()
}

Giveaways should be a nested document in the document with the server's information. My schemas for this looks like this:

const mongoose = require("mongoose");

const giveawaySchema = new mongoose.Schema({  
    identifier: String,
    destination: String,
    duration: String,
    price: String,
})

const mainSchema = new mongoose.Schema({
    guild_id: String,
    log_channel_id: String,
    twitterPreferncesType: String,
    twitterPreferncesFollowing: Boolean,
    giveaways: [giveawaySchema],
});

module.exports = mongoose.model("mainSchema", mainSchema);
module.exports = mongoose.model("giveawaySchema", giveawaySchema);

In my Mongo Atlas I have 2 collections mainSchema und giveawaySchema. If I run this code I only get an entry under 'giveawaySchema' consisting of this:

_id: ObjectId(62b4f6374894fb3e7826ca72)
__v:0

I don't get any data in the mainSchema collection. Does anyone know what is the error? Thank you for your help in advance.

in your first code you don't have to put mongoose module between brackets (i don't know if it's okay) and you are importing giveawaySchema not mainSchema because you are overwriting it you should do this

// module.exports = mongoose.model("mainSchema", mainSchema);
// module.exports = mongoose.model("giveawaySchema", giveawaySchema);
// Wrong you are overwriting on the exports 

// do this instead 
const MainSchema = mongoose.model("mainSchema", mainSchema);
const GiveawaySchema = mongoose.model("giveawaySchema", giveawaySchema);
module.exports = {MainSchema,GiveawaySchema}

// and import it like this 
// const { MainSchema,GiveawaySchema} = require('./<pathOfTheFile>')

and if you still have problem just tell me Good luck ...
