在app.js中，我使用npm从youtube视频中获取信息，问题是当我试图将标题和缩略图等关键信息传递到我的index.ejs文件时，它会给我一个数据未定义的错误，我将非常感谢您的帮助。
app.js
const express = require("express")
const bodyParser = require("body-parser")
const youtubeinfo = require("yt-scraper")
const path = require('path')
const app = express()
app.use(bodyParser.json())
app.use(bodyParser.urlencoded({extended: true}))
app.set("view engine","ejs")
app.set('views', path.join(__dirname, '/views'))
app.use(express.static(__dirname + '/public'));
app.get("/",(req,res)=> {
res.render("index")
})
app.post("/convert",(req,res) => {
var url = req.body.url
var data = youtubeinfo.videoInfo(url,
options = { detailedChannelData: true } )
console.log(data)
data.then(data => {
console.log("=== VIDEO INFO ===")
console.log(data)
res.render("index", {datos:data})
}).catch(err => {
console.log("=== ERROR ===")
console.log(err)
console.log("error")
res.render("error")
})
})
app.listen(5000, ()=> {
console.log("server inciated in port 5000")
})

在我的情况下，当我遇到这个错误时，我只需要重新启动我的节点应用程序。希望有帮助。问候
