can't set webdriver

my environment:

• Puppeteer version: 5.5.0
• Platform / OS version: win10 x64
• URLs (if applicable):
• Node.js version: v14.15.0

What steps will reproduce the problem?

let browser = await puppeteer.launch({
    ignoreDefaultArgs: ['--enable-automation']
});
let page = (await browser.pages())[0];
await page .evaluateOnNewDocument(() => {
        Object.defineProperty(window.navigator, 'webdriver', {
          get: () => false,
        });
      });
await this.currentPage.goto('https://www.baidu.com');

When I execute the above code, I get the following error

VM50:6 Uncaught TypeError: Cannot redefine property: webdriver
    at Function.defineProperty (<anonymous>)
    at <anonymous>:6:28
    at <anonymous>:10:19
(anonymous) @ VM50:6
(anonymous) @ VM50:10

I don’t know what caused it

You can try to add argument --disable-blink-features=AutomationControlled when launch the browser:

const browser = await launch({
    // ...
    ignoreDefaultArgs: ['--enable-automation'],
    args: ['--disable-blink-features=AutomationControlled'],
    // ...
 })

It works to me
