1.看起来你这是 [WD Proxy] 报错，
2.正常的日志应该这样的：
[debug] [WD Proxy] Got response with status 200: {"value":{"message":"WebDriverAgent is ready to accept commands","state":"success","os":{"testmanagerdVersion":28,"name":"iOS","sdkVersion":"13.0","version":"13.1.1"},"ios":{"ip":"172.16.132.205"},"ready":true,"build":{"time":"Aug 11 2020 18:19:39","productBundleIdentifier":"com.facebook.WebDriverAgentRunner"}},"sessionId":"6ACDECDD-835C-4801-8893-5F1C472B80A6"}
3.我猜应该是 WebDriverAgent 初始化失败了，你的安卓 SDK 版本应该有问题；
4.你试试重新装一个；

python 代码从上到下执行的，挨个调用不好吗，搞这么多愚蠢的代码太不优雅了，就像 LS 一样，让别人怎么看得下去。
