I am trying to achieve the following:

class User extends Model {
    // Specifically this override
    toJSON() {
        return { ...this.get(), id: undefined };
    }
}
User.init({
  // Attributes here
}, {sequelize});

The previous code uses the Modal class extension to override the toJSON method; however, I am working on a project where I defined most of my modals using sequelize.define like the following:

const User = sequelize.define('User', {
  // Attributes
});

Instead of refactoring all my models to extend the Modal class, is it possible to override my modals methods?

I tried using the getterMethods like so

getterMethods: {
    get: () => {
        return {...this.get(), id: undefined }
    }
}

Sadly I am using TypeScript that could not compile this code since Object is possibly 'undefined'. ts(2532). Thank you for your time.
