When launching a new page with puppeteer-sharp:

var page = await browser.NewPageAsync();
Dictionary<string, string> headers = new Dictionary<string, string>();
headers.Add("user-agent", "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.131 Safari/537.36");
headers.Add("upgrade-insecure-requests", "1");
headers.Add("accept", "text/html,application/xhtml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3");
headers.Add("accept-encoding", "gzip, deflate, br");
headers.Add("accept-language", "en-US,en;q=0.9,en;q=0.8");
await page.SetExtraHttpHeadersAsync(headers);
await page.GoToAsync(fullUrl);

It throws error:
