java.lang.NullPointerException：条目中的空值：lastScrollData=null

问：

我正在使用 Eclipse 编译我的代码，android studio 4.1.2 用于模拟器和 Appium Server。

我的代码：

DesiredCapabilities c=new DesiredCapabilities();
     
c.setCapability("deviceName", "emulator-5554");
c.setCapability("platformName", "Android");
c.setCapability("noReset", "True");
c.setCapability("appPackage", "com.ionicframework.rocassetassuranceapp290415");
c.setCapability("appActivity", "com.ionicframework.rocassetassuranceapp290415.CordovaApp");
    
AndroidDriver<AndroidElement> driver = new AndroidDriver<AndroidElement>(new URL("http://127.0.0.1:4723/wd/hub"),c);

Thread.sleep(5000);
MobileElement el1 = (MobileElement) driver.findElementByXPath("/hierarchy/android.widget.FrameLayout/android.widget.LinearLayout/android.widget.FrameLayout/android.webkit.WebView/android.webkit.WebView/android.view.View/android.view.View/android.view.View/android.view.View/android.view.View[1]/android.view.View[1]/android.view.View[2]/android.view.View[1]/android.widget.EditText");
el1.click();

我得到以下异常：
