我在Vercel上部署了Next.js应用程序，它是空白的。它在本地运行良好。在浏览器控制台上，我可以看到这个错误：
_app-1516aa2c14264726.js:101 Uncaught SyntaxError: Unexpected token '('
我在使用VSCode的_app.js页面上没有看到任何错误。我不知道在哪里查找以及如何调试它。例如，当我输入类似www.example.com/dashboards的页面url时，我可以在Vercel上的函数日志中看到[GET] /dashboards，而不会出现错误。
这是我的_app.js代码：

我遵循@Micky的建议，发现我的next.config.js文件中有一个设置导致了这个错误。我删除了下面的这条线，现在它在安干工作，
swcMinify: true,
谢谢！
在我的案例中经过数小时的各种尝试相信我，每种方法
那是我的谷歌chrome版本我更新了它的工作良好
