我在商店里有一个Android react原生应用程序，在最近的应用程序统计中，我可以看到一些JavaScript异常，我得到了一些错误代码。我已经阅读了寻找一些东西来告诉我我的代码中的错误在哪里，或者当这个错误出现在最终用户但还没有找到解决方案的时候。你知道我该如何解决这个问题吗?或者这篇文章的意思是什么？

没有代码，我很难回答，但这是我的猜测：

当您的代码在某处请求某个变量时，错误提示变量未填充或(尚)不存在。尝试找到'n._currentElement‘和'e.getHostNode'，我建议使用Cmd/Ctrl + F。如果你能找到这些变量的用法，也许你也能找出错误是在哪里产生的。

祝好运!
