[firolimarazaqaqu32440-netizen]

I am trying to set userAgentMetadata?

but cant

test('puppeteer-real-browser', async () => {
    const { page, browser } = await connect(realBrowserOption)


    // Browser-level CDP connection (exposed by the patch)
    // const conn = browser._connection();
        
    // // Listen to a custom Rebrowser event at browser level
    // browser._connection().on('Rebrowser.addRunEvent', (params) => {
    //     console.log('Rebrowser event fired:', params);
    // });

    // // Send a raw CDP command at browser level
    // await browser._connection().send('Emulation.setUserAgentOverride', {
    //     userAgent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36',
    //     acceptLanguage: 'en-US,en;q=0.9',
    //     platform: 'Windows'
    // });
    

    await page.setUserAgent({
        userAgent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/140.0.7339.185 Safari/537.36',
        userAgentMetadata: {
        brands: [
            { brand: 'Google Chrome', version: '140' },
            { brand: 'Chromium', version: '140' },
            { brand: 'Not A Brand', version: '99' },
        ],
        fullVersion: '140.0.7339.185',
        platform: 'Windows',
        platformVersion: '10.0.0',
        architecture: 'x86',
        model: '',
        mobile: false,
        },
        platform: 'Windows',
    });
    
    await page.goto("https://bot-detector.rebrowser.net/", { waitUntil: "domcontentloaded" })
    
    // await page._client().send('Rebrowser.addRunEvent', {
    //     eventName: 'error', 
    //     eventData: 'captcha' 
    // })


    // await client.send('Emulation.setUserAgentOverride', {
    //     userAgent: uaString,
    //     acceptLanguage: 'en-US,en;q=0.9',
    //     platform: 'Win32',
    //     userAgentMetadata // <-- correct place for brands/fullVersionList/mobile/platform
    // });
    // await page.clickAndWaitForNavigation('body')
    // await browser.close()    
    new Promise((resolve) => setTimeout(resolve, 100000));
