我从uiautomator切换到uiatuomator2，当我尝试将send_keys传递到UI中的文本字段时，出现StaleObjectException错误。在我的窥探会话中，appium找到了该元素并单击它，但是抛出了错误并在send_keys命令后挂起。我还有其他具有相似属性的文本字段，可以使用send_keys键入。
如果我手动在文本字段中键入内容，然后使用send_keys，则该方法有效，但当它为空时则无效。我尝试使用不同的选择器，使用睡眠，在send_keys之前单击，没有区别。如果我切换回旧的uiautomator，则可以使用。
Appium日志显示元素存在并且可单击。为什么说我要访问陈旧的元素？请帮忙。
