selenium.common.exceptions.WebDriverException：消息：未知错误：无法从此类窗口确定加载状态

Question

我正在访问Selenium的driver.title。发生以下异常。

        File "features\steps\XXX_Admin_Edit_XXXXX_Steps.py", line 44, in <lambda>
          assert _wait_until(lambda: context.browser.get_title() == xxx_home.get_page_title(), HelperConstants.WAIT_ONE_MINUTE),\
        File "D:\c\behave-tests\2\_work\10\s\features\utilities\Browser.py", line 166, in get_title
          return self.driver.title
        File "c:\program files\python37\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 342, in title
          resp = self.execute(Command.GET_TITLE)
        File "c:\program files\python37\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 321, in execute
          self.error_handler.check_response(response)
        File "c:\program files\python37\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
          raise exception_class(message, screen, stacktrace)
      selenium.common.exceptions.WebDriverException: Message: unknown error: cannot determine loading status
      from no such window
        (Session info: chrome=85.0.4183.121)

我还没有重现错误。

Google几乎没有“无法从此类窗口确定加载状态”的结果

有什么想法吗？
