嵌套验证中的hapi/joi描述性错误

const Joi = require('joi');

const schema = Joi.object({
  username: Joi.string().required().error(new Error('用户名不能为空')),
  password: Joi.string().required().error(new Error('密码不能为空')),
  email: Joi.string().email().required().error(new Error('邮箱格式不正确')),
  address: Joi.object({
    street: Joi.string().required().error(new Error('街道不能为空')),
    city: Joi.string().required().error(new Error('城市不能为空')),
    zip: Joi.string().required().error(new Error('邮编不能为空')),
  }),
});

const data = {
  username: 'john',
  password: 'password',
  email: 'john@example.com',
  address: {
    street: '123 Main St',
    city: 'New York',
    zip: '12345',
  },
};

const result = schema.validate(data);

if (result.error) {
  console.log(result.error.message);
} else {
  console.log('验证通过');
