Node.js 不允许使用父数组JOI npm库

Hi-im使用Joi在简单API上验证JSON对象，我的验证模式是：

let holidays = Joi.object().keys({
    day: Joi.number().required(),
    month: Joi.number().required(),
    description: Joi.string().required()
})

const countryValidateSchema = Joi.object().keys({
    name: Joi.string().required(),
    holidays: Joi.array().items(holidays),
    states: Joi.array().required().items(Joi.string())
});

当添加一个新国家时，我会这样验证：

function newCountry(req, res) {
    //TODO validate
    var newCountry = new Country(req.body);

    const result = Joi.validate(newCountry, validate.countryValidateSchema);
    const { value, error } = result; 
    const valid = error == null; 

    if (!valid) { 
      res.status(422).json({ 
        message: result, 
        data: newCountry 
      }) 
    } else { 
        //Store on DB
        newCountry.save((err,country) =>{
            if(err){
                res.send(err);
            }else{
                res.status(201).json({message: "Country successfully added!", country})
            }
        });
    }
}

当我尝试使用此JSON添加新国家/地区时，会抛出错误： 不允许使用父数组

有什么想法吗？

解决后，我验证的是一个Country对象，而不是json主体。因此，解决办法是改变

var newCountry = new Country(req.body);

到

var newCountry = new Country(req.body);

var newCountry = req.body;
