Вопрос:

У меня есть 3 поля, которые по умолчанию не требуются. Однако правило требует, чтобы, если указано какое-либо из 3 полей, то все 3 будут обязательными.

Пример field_1, field_2 и field_3

 validataionSchema = Yup.object({
  title: Yup.string().max(10, "Max character exceeded").required("This field is required"),
  field_1: Yup.string().max(32, "Max character exceeded"),
  field_2: Yup.string().max(32, "Max character exceeded"),
  field_3: Yup.string().max(32, "Max character exceeded"),
})
  

Я пробовал

 
validataionSchema = Yup.object({
  title: Yup.string().max(10, "Max character exceeded").required("This field is required"),
  field_1: Yup.string().max(15, "Max character exceeded")
    .when(['field_2', 'field_3'], {
      is: (field_2, field_3) => {
        console.log("* field_2, field_3", field_2, field_3)
        return true
      },
      then: Yup.string().required("This field is required")
    }),
  field_2: Yup.string().max(64, "Max character exceeded")
    .when(['field_1', 'field_3'], {
      is: (field_1, field_3) => {
        console.log("** field_1, field_3", field_1, field_3)
        return true
      },
      then: Yup.string().required("This field is required")
    }),
  field_3: Yup.string().max(64, "Max character exceeded")
    .when(['field_1', 'field_2'], {
      is: (field_1, field_2) => {
        console.log("*** field_1, field_2", field_1, field_2)
        return true
      },
      then: Yup.string().required("This field is required")
    }),
})
  
  

Но я получаю Error: Cyclic dependency, node was:"field_2"

В интересах всех, кто может быть заинтересован в решении

   field_1: Yup.string().max(15, "Max character exceeded")
    .test("field_1", "This field is required as part of Fields details", function(value) {
      let f2 = this.resolve(Yup.ref("field_2"));

      if ((typeof value === "undefined" amp;amp; typeof f2 === "undefined" amp;amp; typeof f3 === "undefined") || typeof value !== "undefined") {
        return true
      }
      return false;
    }),
