似乎找不到正确的元素，或者我试图将返回的元素强制转换为错误的类型。寻找正确的语法以找到一个点击它的按钮。我正在使用iOS模拟器构建Appium，并使用Java客户端运行测试。
@Test (enabled=true) public void myFirstTest() throws InterruptedException {
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
**IOSElement button = driver.findElement(MobileBy.AccessibilityId("UIA_upsellPage_third_button"));**
org.openqa.selenium.WebDriverException: Returned value cannot be converted to WebElement: {element-6066-11e4-a52e-4f735466cecf=28000000-0000-0000-61D4-000000000000, ELEMENT=28000000-0000-0000-61D4-000000000000}

预期结果： 应该返回一个可以用模仿按钮按下方法的元素。
实际结果：org.openqa.selenium.WebDriverException: Returned value cannot be converted to WebElement: {element-6066-11e4-a52e-4f735466cecf=28000000-0000-0000-61D4-000000000000, ELEMENT=28000000-0000-0000-61D4-000000000000}
