[Joi] callStack: Error: item added into group finishDate created a dependencies error\n

Joi 를 사용하다가 나온 에러 

Joi callStack: Error: item added into group finishDate created a dependencies error\n 

 

 

My code :

const validationSettings = {
  index: Joi.number().integer().required().label('index'),
  startDate: Joi.date()
    .format('YYYY-MM-DD')
    .min(
      Joi.ref('finishDate', {
        adjust: finishDate => new Date(finishDate.setDate(finishDate.getDate() - 89)),
      }),
    )
    .label('startDate'),
  finishDate: Joi.date().format('YYYY-MM-DD').max(Joi.ref('startDate')).label('finishDate'),
};

 

 

 

Error: 

{
    "error": {
        "status": 500,
        "name": "Error",
        "message": "item added into group finishDate created a dependencies error"
    }
}

 

Joi.ref() 를 사용할 때 A->B, B->A이렇게 순환 구조로 서로를 바라보게 하면 위와 같은 에러가 난다고 한다. 둘 중 하나를 다른 매서드로 대체해야한다. Joi.Ref -> max('now')로 변경하니 해결되었다. 

 

The reason was because I used Joi.ref('fihishDate') in startDate and Joi.ref('startDate') in finishDate. You can't create a circular dependency. You need to use object assert. 

I used max('now') instead of Joi.ref()

  finishDate: Joi.date().format('YYYY-MM-DD').max('now').label('finishDate'),

And now it works !@
