Question

这是我在heroku部署中的第一次尝试，因此即使构建成功，我仍会遇到应用程序错误，这是我尝试在heroku上部署的现代应用程序，并且在本地服务器上也能正常运行。这是来自heroku网站的日志

我整天都在搜索，没有mongodb的连接，我以为是什么问题。我可以提供进一步的信息，而且当我登录npm时，它更加精巧；

index.js

if (process.env.NODE_ENV === "production") {
  
  app.use(express.static("client/build"));

  app.get("*", (req, res) => {
    res.sendFile(path.resolve(__dirname, "client", "build", "index.html"));
  });
}

const port = process.env.PORT || 5000;

app.listen(port, () => {
  console.log(`Server Listening on ${port}`);
});

在“构建成功”之后出现Heroku应用程序错误
