我正在使用passport.js作为一个简单应用程序的身份验证系统。用户输入用户名和密码以进入系统。用户登录后，在addtodb.ejs或editdb2.ejs页面上提交表单时，表单不会提交，用户将注销。有时候，表单很少会被提交，但不管怎样，用户最终都会被注销。当您花整整两分钟处理表单时，表单提交的注销会持续发生。如果少于两分钟，有时你会得到相同的行为，但在两分钟和超过分数时是一致的。
代码包括在下面。我尝试了许多关于stackoverflow的建议。
server.js：

const mongoose = require("mongoose");
const express = require("express");
const app = express();
