setDataSourceFD 失败：状态=0x80000000

如何解决setDataSourceFD 失败：状态=0x80000000

我正在开发一个录音并播放它的应用程序，但我遇到了问题。我希望我的应用程序录制音频，当我点击它时应该停止。它可以录制语音，但点击按钮后它会崩溃。我已经检查了与它相关的所有链接。在过去的 2 天里，我一直在尝试修复此错误。请帮帮我。

这是我的代码

./src/index.js
SyntaxError: E:\REACT_APP\drf_project\src\index.js: Identifier 'routing' has already been declared (25:13)

  23 | serviceWorkers.unregister();
  24 | 
> 25 | export const routing
     |              ^
