问题：打开微信连续侧滑，第一页可以滑动，到第二页再滑动就报错
部分代码：

@driver= Appium::Driver.new(caps)
@touch = Appium::TouchAction.new
@dirver.start_driver
@touch.swipe(start_x:1000,start_y:300,end_x:300,end_y:300,duration:1000).perform
@touch.swipe(start_x:1000,start_y:300,end_x:300,end_y:300,duration:1000).perform

我分析第二次滑动失败，是因为（日志）

info: --> POST /wd/hub/session/c19b459b-8c06-4ee4-9de4-f4c25a483bdf/touch/perform {"actions":[{"action":"press","options":{"x":1000,"y":300}},{"action":"wait","options":{"ms":200}},{"action":"moveTo","options":{"x":300,"y":300}},{"action":"release"},{"action":"press","options":{"x":1000,"y":300}},{"action":"wait","options":{"ms":200}},{"action":"moveTo","options":{"x":300,"y":300}},{"action":"release"}]}
跟第一次（日志）相比多了
{"action":"press","options":{"x":1000,"y":300}},{"action":"wait","options":{"ms":200}},{"action":"moveTo","options":{"x":300,"y":300}},{"action":"release"}
导致服务不响应

尝试过的解决办法：
1.延长等待以及程序睡眠时间
2.升级 appium_lib 到最新版

问题依然存在，哪位同学也碰到过这样的问题，求分享！
