Oct 8 07:57:38 PM at Module.\_compile (internal/modules/cjs/loader.js:1068:30)我的index.js代码是：
const express = require("express");
const {sl} = require("./sl");
const app = express();
const PORT = process.env.PORT || 4000;
app.get("/scrape", (req, res) => {
sl(res);
})
app.get("/", (req, res) => {
res.send("Render Puppeteer server is up and running!");
})
app.listen(4000, () => {
console.log(`Listening on port ${PORT}`)
})我的ScrapeLoading代码是：
const express = require("express");
const {sl} = require("./sl");
const app = express();
const PORT = process.env.PORT || 4000;
app.get("/scrape", (req, res) => {
sl(res);
})
app.get("/", (req, res) => {
res.send("Render Puppeteer server is up and running!");
})
app.listen(4000, () => {
console.log(`Listening on port ${PORT}`)
})另外，我已经更新了puppeteer和node.js

我在Node.js Web应用程序中使用Puppeteer下载PDF时遇到错误。这似乎是一个语法错误，我花了很多时间查看我的代码来确定问题。最终，我发现这个问题与我的“Node.js版本不是最新的”有关。Puppeteer不支持我正在使用的版本。一旦我更新了我的Node.js和Puppeteer，这个问题就解决了。
