Set RequestHeader through Selenium WebDriver

Question

I'm encountering the below error while trying to set Request headers using browsermobproxy for selenium tests.

Exception in thread "main" org.openqa.selenium.WebDriverException: : Failed to read the 'localStorage' property from 'Window': Access is denied for this document.

Driver program

public static void main(String[] args) throws Exception {
        System.setProperty("webdriver.chrome.driver", "C:\\Try\\drivers\\chromedriver.exe"); //PropertyReader.getProperty("chromedriverpath")
        
         // start the proxy
        BrowserMobProxy proxy = new BrowserMobProxyServer();
        proxy.setTrustAllServers(true);
        proxy.start(0);

        // get the Selenium proxy object
        Proxy seleniumProxy = ClientUtil.createSeleniumProxy(proxy);
        
        String chromeProfilePath = "C:\\Users\\AppData\\Local\\Google\\Chrome\\User Data\\Default";
        
      //capabilities
        ChromeOptions options = new ChromeOptions();
        options.addArguments("--disable-web-security");
        options.addArguments("--ignore-certificate-errors");
        options.addArguments("--user-data-dir="+chromeProfilePath);
                                                                
        
        // configure it as a desired capability
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability(CapabilityType.PROXY, seleniumProxy);
        capabilities.setCapability(ChromeOptions.CAPABILITY, options); 
        //capabilities.setCapability("disable-web-security", true);

        // start the browser up
        WebDriver driver = new ChromeDriver(capabilities);

        // enable more detailed HAR capture, if desired (see CaptureType for the complete list)
        proxy.enableHarCaptureTypes(CaptureType.REQUEST_CONTENT, CaptureType.RESPONSE_CONTENT);

        //
        driver.get("chrome-extension://idgpnmonknjnojddfkpgkljpfnnfcklj/_generated_background_page.html");
        
        
        String jsScript = "localStorage.setItem('profiles', JSON.stringify([{  title: 'Selenium', hideComment: true, appendMode: '', \n" +
                  "             headers: [                        \n" +

                  "             ],                          \n" +
                  "             respHeaders: [],\n" +
                  "             filters: []\n" +
                  "          }]));";
        
        
        ((JavascriptExecutor)driver).executeScript(jsScript);

          
    // create a new HAR with the label "yahoo.com"
    proxy.newHar("localhost:4200");

    // open app
    driver.get("http://localhost:4200/app/");

It would be great if anyone can help me on this. Thank you.

This is because your browser privacy settings disallow javascript on the page to set up cookies (third-party cookies). You need to change them using properties.
