typescript - Yup.mixed() 验证未验证

Question

我有一个使用 react-hooks-form 的表单，我为我制作了一些组件，例如文本框、文本区域、选择……这些都是受控组件。现在在我的表单中，我使用 Yup 进行验证，并且有一点它不起作用。在我的表单中，我有一个动态输入类型（queryParam），它根据组选择的值而变化，它可以是文本框或选择。当 group 为 1 时，不需要queryParam，但如果 group 的值大于 1 则显示字段，我需要输入queryParam的值，但它没有验证，我无法按下按钮。queryParam可以是来自文本框的文本，也可以是来自 select 的字符串形式的数字。

我的验证模式：

import * as Yup from "yup";

export const validationSchema = Yup.object().shape
({
      text: Yup
            .string()
            .required()
            .max(2048, "Az üzenet szövege túl hosszú,"),
      groupID: Yup
              .number()
              .required(),
      queryParam: Yup
                 .string()
                 .when("groupID",
                 {
                        /*** THIS PART NOT WORKING ***/
                        is: (groupID: number) => groupID > 1,
                        then: Yup.mixed()
                                 .required("Kötelező mező.")
                  }),
      isVoteType: Yup
                 .boolean(),
      positiveAnswer: Yup
                      .string()
                      .when("isVoteType",
                      {
                              is: (isVoteType: boolean) => isVoteType,
                              then: Yup.string()
                                       .required("Kötelező mező.")
                      }),
      negativeAnswer: Yup
                      .string()
                      .when("isVoteType",
                      {
                              is: (isVoteType: boolean) => isVoteType,
                              then: Yup.string()
                                       .required("Kötelező mező.")
                      })
});

这是我最后所做的：

import * as Yup from "yup";

export const validationSchema = Yup.object().shape

            .required("Kötelező mező.")

      groupID: Yup
              .number()
              .min(1, "Kötelező mező.")
              .required("Kötelező mező."),
      queryParam: Yup
                 .mixed()
                 .when("groupID",
                 {
                        is: (groupID: number) => groupID > 1,
                        then: Yup.lazy( (value: any) =>

                          console.log("value: ", value);
