我有一个字段数组组件，它处理一个数组值，这个数组值可以在不同的表单中嵌套在不同的层次上。我把表单控件和名称传递给它，以得到这个值。在v7中，我不能正确地输入它。
这是我的代码的一个简化示例，它工作得很好，但引发了TS错误：

import { Control, useFieldArray } from "react-hook-form";

interface Item {
  key: string;
}
interface A {
  items: Item[];
}
interface B {
  data: {
    items: Item[];
  };
}
interface ItemFormFieldsProps<TControl extends Control<A> | Control<B>> {
  control: TControl;
  name: TControl extends Control<A> ? "items" : "data.items";
}

const ItemFormFields = <TControl extends Control<A> | Control<B>>({
  control,
  name,
}: ItemFormFieldsProps<TControl>) => {
  const { fields } = useFieldArray({
    control,
    ^^^^^^^^
    name,
    ^^^^^
  });
};

对于control，我遇到以下错误：

对于name：
