The primary key field is defined using the idProperty of the model, which must match one of the field names. The User model can now be updated as shown:

    fields: [
        { name: 'username', type: 'string' },
        { name: 'firstName', type: 'string' },
        { name: 'lastName', type: 'string' },
        { name: 'fullName', type: 'string' },
        { name: 'email', type: 'string' },
        { name: 'password', type: 'string' },

});
