Cannot get page content using puppeteer ? #365
Description
hi,
i am trying to get page content/html but i am getting error Error [ReferenceError]: XMLSerializer is not defined
i am using docker for running the script, from inside docker i can dump the content of url with command line usage
EDIT: i tried same code with "cloud.lightpanda.io" its also not working using browser=lightpanda
my code
import puppeteer from "puppeteer-core"
let url = "https://www.wikipedia.org/"
// use browserWSEndpoint to pass the Lightpanda's CDP server address.
const browser = await puppeteer.connect({
browserWSEndpoint: "ws://127.0.0.1:9222",
})
// The rest of your script remains the same.
const context = await browser.createBrowserContext()
const page = await context.newPage()
await page.goto(url)
const html = await page.content()
console.log("html :>> ", html)
await page.close()
await context.close()
await browser?.disconnect()
error
