method setExtraHTTPHeaders doesn't work

[adultviews20]

Hi could someone help me , what the problem can be.
I am launching instance of browser by puppeteer for dart, but extra headers doesnt want to apply, i set it and then check by website online checker for headers ( tried different websites)

my scenario very simple

---

List argsPup = [
// '--no-sandbox',
// '--disable-setuid-sandbox',
'--disable-infobars',
'--window-position=0,0',
'--ignore-certifcate-errors',
'--ignore-certifcate-errors-spki-list',
'--proxy-server=global.rotating.proxyrack.net:9000',
'--lang=en-US',
'--no-first-run',
'--no-service-autorun',
'--password-store=basic',
'--disable-gpu',
'--disable-infobars',
'--disable-dev-shm-usage',
'--disable-browser-side-navigation',
'--disable-breakpad',
'--use-mock-keychain',
'--disk-cache-dir=/dev/null',
'--media-cache-dir=/dev/null',
'--disk-cache-size=0',
'--media-cache-size=0',
'--disable-application-cache',
'--disable-component-extensions-with-background-pages',
'--disable-features=TranslateUI,BlinkGenPropertyTrees',
'--allow-insecure-localhost',
'--ignore-ssl-errors',
'--ssl-insecure',
'--disable-popup-blocking',
'--incognito',
'--window-size=1280,960',
"--disable-features=NetworkService"
// '--disable-blink-features=AutomationControlled',
];

browser = await puppeteer.launch(
ignoreDefaultArgs: [
'--enable-automation',
'--enable-blink-features=IdleDetection'
],
args: argsPup,
headless: false,
);

---

then i setting user agent

---

await page.setUserAgent(userAgent);

---

then i adding headers

await page.setExtraHTTPHeaders({
  'Accept-Language': 'en-US;q=1',
  'SEC-CH-UA-PLATFORM-VERSION': '10.0.0',
  'SEC-FETCH-SITE': 'cross-site',
  'Sec-CH-UA-Platform': "Windows",
  'SEC-CH-UA-MODEL': '',
  'SEC-CH-UA-MOBILE': '0',
  'SEC-CH-UA-FULL-VERSION': '119.0.6045.200',
  'SEC-CH-UA-ARCH': 'x86',
  'SEC-CH-UA': '',
  'SEC-CH-PREFERS-REDUCED-MOTION': 'no-preference',
  'SEC-CH-PREFERS-COLOR-SCHEME': 'light',
  'ACCEPT-ENCODING': 'gzip, deflate, br',
  // 'CACHE-CONTROL' : 'no-cache, max-age=0',
  'RTT': '50',
  'DPR': '1.25',
  'DOWNLINK': '9.25'
});

thens some few more settings and traffic filter and proxy auth

await page.emulateTimezone('America/New_York');
await page.setJavaScriptEnabled(true);

try {
**await page.setRequestInterception(true);**
page.onRequest.listen((request) async {
  if (
    request.url.endsWith('.webp') ||
          request.url.endsWith('.jpg') ||
          request.url.endsWith('.jpeg') ||
          request.url.endsWith('.css')||
          request.url.endsWith('.gif') ||
          request.url.endsWith('.svg') ||
          request.url.endsWith('.mp4') 
   
      ) {
    await request.abort();
  } else {
    await request.continueRequest();
  }
});

} catch (e) {}

page.authenticate(
username: 'natalyportman',
password: '*************');

FINALLY i go to the website headers checker, doesnt want to change, i try to do it one by one, its work only for 'ACCEPT-ENCODING'
