Do you know if Puppeteer Extra package handles this? https://github.com/berstend/puppeteer-extra

[zelbov]

page.evaluateOnNewDocument(() => {

        class ModifiedError extends Error {

            constructor(message) {

                super(message)
                this.stack = this.stack.replace(
                    /at __puppeteer_evaluation_script__.*/gmi, 'at (window)'
                )

            }

        }

        Object.defineProperty(window, 'Error', { configurable: false, writable: false, value: ModifiedError })

})

checkmate =)

Hey Vladislav, is that script stopping the detection of Puppeteer like it's stated by author of this repo?

[zelbov]

yep. it overlaps native Error object with child class which replaces detected string in stack trace on error initialization, and prevents further overlapping of Error object, before any other script will be executed on page

Thank you for explanation!

Any chance you can help with playwright version? I have used this

page.addInitScript(() => {
        class ModifiedError extends Error {
            constructor(message) {
                super(message)
                this.stack = this.stack.replace(
                    /at __playwright_evaluation_script__.*/gmi, 'at (window)'
                )
            }
        }        
        Object.defineProperty(window, 'Error', { configurable: false, writable: false, value: ModifiedError })        
    })

But than almost all youtube buttons stop working. For example when I click "upload" or "Youtube studio" nothing happens except bunch of errors in console.
