目前正在使用Visual Studio-2017并安装了Appium Webdriver。 为Windows Calculator准备代码时出现以下错误:

An exception with a null response was thrown sending an HTTP request to the remote WebDriver server for URL http://10.206.8.232:169/wd/hub/session. The status of the exception was ServerProtocolViolation, and the message was: The server committed a protocol violation.
在生产线上:

RemoteWebDriver driver = new RemoteWebDriver(new Uri("http://10.245.12.81:139/wd/hub"), caps);
我希望打开Windows计算器并执行该操作
