我的 PHP 表单和 express js app api 有错误

Question

我试图创建一个端点 API，当通过我的 PHP 网站发送发布请求时，它会在托管 Express 应用程序的服务器上本地更新文件。

我在发送表单数据时遇到错误...

报错如下： API错误：

Error: Invalid request data
    at Settings.handleSettingsRequest (/root/API/index.js:264:19)
    at Layer.handle [as handle_request] (/root/API/node_modules/express/lib/router/layer.js:95:5)
    at next (/root/API/node_modules/express/lib/router/route.js:144:13)

我的代码如下：

我可能只是个白痴，但是是的，我想不通，我已经尝试了很多。我尝试删除特定项目，例如启用白名单的设置，因为我认为这是最有可能导致问题的
