Model.find is not a function mongoose - node.js

Question

I have a mini casino game and have a mongoose model defined as following:
const jackpotSchema = mongoose.Schema({
round_id: {
type: String,
default: uniqid(),
required: true,
},
createdAt: {
type: Date,
required: true,
default: Date.now
},
closedAt: {
type: Date,
},
startedAt: {
type: Number,
},
roundSecret: {
type: String,
required: true,
},
random_org_hash: {
type: String,
},
random_org_obj: {
type: String
},
roundSecretHash: {
type: String,
},
winningPercentage: {
type: Number,
// required: true,
// first 5 characters of the secret hash, converted into decimal then divided by 10K
},
publicHash: {
type: String,
required: true,
// SHA-256 roundSecret + winningPercentage
},
finalHash: {
type: String,
},
winningTicket: {
type: Number,
},
winningDepositIndex: {
type: Number,
},
deposits: [{
uid: {
type: String,
required: true,
},
user: {
type: String,
required: true,
},
nonce: {
type: Number,
},
amount: {
type: Number,
required: true,
},
user_avatar: {
type: String,
},
ticketRangeMin: {
type: Number,
required: true,
},
ticketRangeMax: {
type: Number,
required: true,
},
referral: {type: String},
timestamp: {type: Date},
timestamp_readable: {type: String}
}],
total: {
type: Number,
required: true,
default: 0,
},
totalTickets: {
type: Number,
default: 0,
},
winner: {
type: String,
default: "",
},
winner_avatar: {
type: String,
},
active: {
type: Boolean,
default: true,
required: true,
},
open: {
type: Boolean,
required: true,
default: true,
},
roundTime: {
type: Number,
// default: potConfig.potLength,
default: 20000,
},
success: {
type: Boolean,
},
fee: {
type: Number,
default: potConfig.potFee,
}
})
module.exports = mongoose.model("Jackpot", jackpotSchema)
When running my app locally, I experience no errors.
However when running on a ubuntu production environment, I get the following error:
Jackpot.find is not a function
The stack trace says that the error is coming from db_utils.js
which looks like the following:
const Jackpot = require("./models/Jackpot");
...
async retrieveStats () {
var jackpots = await Jackpot.find().lean();
}
I have checked to see whether my module.exports was defined correctly, and it is. Not sure why this error is happening.
My local and production node versions match.

Don't you need to do
const jackpotSchema = new mongoose.Schema({...})
instead of
const jackpotSchema = mongoose.Schema({...})
