Must be invoked on a Joi instance.

Hi, I try to use your package on front-end and get the following error

I imported the package in following way:

import validator from 'cpf-cnpj-validator';
const Joi = require('@hapi/joi').extend(validator);

I'm getting the same error

Same here using Vuejs

import { cpf, cnpj } from 'cpf-cnpj-validator';

const validateCpfCnpj = function (value) {
  if (value.length == 11 && cpf.isValid(value)) {    
    return true;
  } else if (value.length == 14 && cnpj.isValid(value)) {
    return true;
  } else {
    return false;
  }  
}

I made a correction, you can try like this

import J from '@hapi/joi';
import { validator } from 'cpf-cnpj-validator';

const Joi = J.extend(validator);
