appium測試，記錄在原生的context获取window handler 就会报错Proxy error: Request failed with status code 404

問題：在測試APP混合頁面的時候查詢當前窗口句柄會導致程序報錯如下

selenium.common.exceptions.WebDriverException: Message: An unknown server-side error occurred while processing the command. Original error: Could not proxy. Proxy error: Request failed with status code 404
C:\Python37\lib\site-packages\selenium\webdriver\remote\errorhandler.py:242: WebDriverException

代碼如下：

from selenium.webdriver.support.wait import WebDriverWait
