StrictModeError on using upsert with updateOne in Mongoose - node.js

Question

I want to add a list of users in DB if they do not exist in DB and skip for the ones which already exists, for this, I am using writeMany operation with updateOne and upsert set as true. But it gives me StrictModeError.
Here is the function which creates the insertMany
const bulkWriteData = blacklistData.map(value => {
return {
updateOne : {
upsert: true,
filter : {
email : value
},
update : {
$set : {
_id : mongoose.Types.ObjectId(),
status : STATUS.BLOCKED,
createdAt : new Date(),
updatedAt : new Date()
}
}
}
}
})
await EmailUsers.bulkWrite(bulkWriteData)
Here is the EmailUsers Model
const mongoose = require('../config/connection')
const Schema = mongoose.Schema
const validator = require('../utils/validator.util')
const uniqueValidator = require('mongoose-unique-validator')
const EmailUsers = new Schema({
email: {
type: String,
required: true,
validate: validator.mongooseEmailValidator,
unique: true,
},
status: {
type: String,
enum: ['active', 'bounced'],
required: true,
default: 'active',
},
createdAt: {
type: Date,
required: true,
default: () => new Date(),
},
updatedAt: {
type: Date,
required: true,
default: () => new Date(),
},
bounceResponse: [
{
type: Object,
required: false,
},
],
})
EmailUsers.index({ email: 1, status: 1 })
EmailUsers.plugin(uniqueValidator, { type: 'mongoose-unique-validator' })
module.exports = mongoose.model('email_users', EmailUsers)
This is the validator used for email
const mongooseEmailValidator = validate({
validator: 'matches',
arguments: constants.regex.email,
message: 'Email should be a valid email address',
})
Here is the array which was sent to bulkwrite
[{
updateOne : {
upsert : true,
filter : { email: 'test#gmail.com' },
update : {
'$set': {
_id: 607ec7fd009fc824c5c34b5d,
status: 'blocked',
createdAt: 2021-04-20T12:24:29.693Z,
updatedAt: 2021-04-20T12:24:29.693Z
}
}
}
}]
Here is the error
error: Path "email" is not in schema, strict mode is `true`, and upsert is `true`. {"trace":"StrictModeError: Path \"email\" is not in schema, strict mode is `true`, and upsert is `true`.\n at cast
This doesn't make sense as I do have email in the schema
This actually updates the DB with the data and then throws the error.
What could be the possible solution?
