今天手贱，升级了最新的 appium1.8.1 以及 WebDriverAgent, 然后，click element 就报错了

selenium.common.exceptions.WebDriverException: Message: An unknown server-side error occurred while processing the command. Original error: Could not proxy. Proxy error: Could not find :session section for url: /wd/hub/session/2649babb-b1d9-483a-af2e-fe7873abe92b/element/1D000000-0000-0000-3F01-000000000000/click

有没有大神也碰到了这样的问题，求教！!!!

附上 Appium server log:
