Javascript Reactjs ERR\u无效的参数类型

那里！ 我从最早的网站上买了一些模板，预览版的一切都很好，但新的版本出现了类似这样的错误

我相信模板不应该有这个错误，但我仍然有它。可能是什么问题？

您可以查看此链接

要解决此问题，只需升级到react脚本：^3.4.0

使用包中的react脚本“^3.4.0”覆盖现有的react脚本“^3.x.x” 删除节点模块 最后在命令提示符下运行npm安装或纱线安装。 我希望它能修复它。

您需要提供代码。从表面上看，它抱怨validators.js在函数validateString中路径参数未定义。请检查此回复，您需要提供代码。从表面上看，它抱怨validators.js函数中的validateString路径参数未定义。请检查此回复
