未能找到值字段

雖然執行Java腳本代碼來顯示警報，我得到「無法找到值字段」在第二行異常。

代碼：

 IJavaScriptExecutor js = driver as IJavaScriptExecutor;  
     js.ExecuteScript("alert('Complete human verification.')");  
     Thread.Sleep(30000);

例外：

System.InvalidOperationException was unhandled by user code 
    HResult=-2146233079 
    Message=Failed to find value field

這似乎是一個geckodriver錯誤，並沒有解決這個問題。 – Black
