如何确定nextjs子级是否为字符串

在升级到下一个13代码之前,代码工作正常,现在我在vsode中得到这个typescript错误,buttonProps的类型是“ReactI18NextChild”类型|Iterable'.堆栈溢出说我必须添加更多的细节,因为我的帖子主要是代码。
“ReactI18NextChild”类型的参数|Iterable“不能赋给”ReactNode“类型的参数|[]“中定义。

import React, { ButtonHTMLAttributes } from 'react';
import { ReactI18NextChild } from 'react-i18next';
import { parseBackgroundColor, parseColor, parseBorderColor, parseFontSize } from 'styles/styles';

interface Props extends ButtonHTMLAttributes<HTMLButtonElement> {
    otherProps
}

function Button({ otherProps, ...buttonProps }: Props) {
    const isString = React.Children.toArray(buttonProps.children).some(child => {
      if (
        typeof child === 'string' ||
        typeof child === 'number' ||
        ((child as any)?.type && ['span', 'p', 'h1', 'h2', 'h3', 'h4', 'h5', 'h6'].includes((child as any).type))
      ) {
        return true;
      }
    });

    return <button>{buttonProps.children}</button>
}

此错误的原因是react-i18next的类型定义。react-i18next类型定义文件中存在某些interface扩充,这些扩充会重写现有类型。
问题在于:

type ObjectOrNever = TypeOptions['allowObjectInHTMLChildren'] extends true
  ? Record<string, unknown>
  : never;
type ReactI18NextChild = React.ReactNode | ObjectOrNever;

declare module 'react' {
  interface HTMLAttributes<T> {
    children?: ReactI18NextChild | Iterable<ReactI18NextChild>;
  }
}

由于某种原因,children被覆盖为ReactI18NextChild | Iterable<ReactI18NextChild>类型。并且ReactI18NextChild将此ObjectOrNever类型包括在具有可能的Record<string, unknown>输出类型的联合中。并且Record<string, unknown>无法分配给React.ReactNode,从而导致错误。
我个人建议现在只使用类型Assert:

const isString = React.Children.toArray(
  buttonProps.children as React.ReactNode
).some(child => {
  /* ... */
});

或者完全删除react-i18next导入(如果可能)。
无论哪种方式,你都可以在Github上打开一个关于这个问题的问题。这可能是也可能不是缩进的行为,特别是如果在更新之前这是有效的。
