Screenshots are not appearing in Selenium Java TestNg project. I have used the below version of dependencies in pom.xml.

<selenium.version>4.22.0</selenium.version>
<testng.version>7.10.2</testng.version>
<allure.version>2.28.0</allure.version>
<aspectj.version>1.9.19</aspectj.version>

In Listener class, I have created the below methods to capture screenshot and to attach screenshot on test failure.

@Attachment(type = "image/png")
    public byte[] saveFailureScreenshot(WebDriver driver){
        return ((TakesScreenshot) driver).getScreenshotAs(OutputType.BYTES);
    }
    @Attachment(value = "{0}", type = "text/plain")
    public static String saveTextLog(String message){
        return message;
    }
@Override
public void onTestFailure(ITestResult result) {
    Logs.error("Exception occurred: " + result.getThrowable());
    Logs.error("************ Test Case failed************"+getTestMethodName(result));
    WebDriver driver = getDriver();
    if(driver != null){
        Logs.info("Capturing screenshot for "+getTestMethodName(result));
        saveFailureScreenshot(driver);
        ITestListener.super.onTestFailure(result);
    }
    saveTextLog(getTestMethodName(result)+ " failed and screenshot captured.");
}

But reports are generated without screenshots.
