在将数据从表单传递到NodeJS中的URL时遇到频繁错误，该错误无法发布/ urlname

如何解决在将数据从表单传递到NodeJS中的URL时遇到频繁错误，该错误无法发布/ urlname

这是我的发件人页面，我在其中发布到URL文章，但出现错误，无法发布POST / URL名称 每次我想保存一篇新文章时，都会出现相同的错误，无法发布/ URL名称

 <form action="/routes/articles" method="post">
                   //here I simply used a partials!
                            {{>form}}
                    
                        </form>
        this is code where I get data through post method that is mentioned and then it is saved to the database const express = require('express');
                    const router = express.Router();
                    const Article = require("../model/schema")
                    router.get('/',(req,res) => {
                      res.send('hey !!');
                    });
                    
                    router.get('/new',res) => {
                      res.render('articleGenerator');
                    }); 
                    router.get("/:id",res)=>{
                    })
                  
                    router.post("/",async(req,res)=>{
                    
                    const newArticle = new Article({
                    
                    title:req.body.title,description:req.body.description,markdown:req.body.markdown
                    })
                    //this code saves new article that is send from form page mentioned above
                    try {
                      newArticle = await newArticle.save();
                      res.redirect(`/articles/${newArticle.id}`)
                    } catch (error) {
                      
                      res.render("/articleGenerator",{articles:newArticle});
                    
                    }
                    })

这是我运行的主文件请注意，我已经导出了一个保存数据的路由articlejs。 module.exports =路由器;

                        const express = require('express');
                    const app = express();
                 
                    const mongoose = require("mongoose");
       this is for data base mongoose//
                    mongoose.connect("mongodb://127.0.0.1:27017/blogging-site",{
                      useNewUrlParser:true,useUnifiedTopology:true,useCreateIndex:true
                    })
                    //here i get the routes of page that is saving the data
                    const theRoutes = require('./routes/articles')
                    app.use('/theroutes',theRoutes);
                    app.set('view engine','hbs');
                    
                    app.get('/',res) => {
                      res.render('index');
                    });
                
                    app.listen(3000,() => {
                      console.log('server is up and running!!');
                    });
