I am trying to accept an alert but , getting an error like "Unable to accept Alert"

Question

I am getting an error when trying to accept an alert. I tried getting the alert text message from the alert. I was able to get the message using WebUI.getAlertText() after adding the below details in Project> WebUI Chrome Settings

Version Details : Chrome browserVersion: 107.0.5304.122 chromedriverVersion: 107.0.5304.62

But still I am unable to accept or decline the alert.

I also tried using WebDriver:

//WebDriver myDriver = DriverFactory.getWebDriver()

//myDriver.switchTo().alert().accept(); ** Still facing the error. Please help...

Any other settings to be made? ** Error Details as below:

Try adding some waiting time for the alert to be present:

WebUI.waitForAlert(20)
