Continuous use of Appium :: TouchAction to create an object, Appium server reported Http Code (500)

[swmvp]

I want to open an app, slide left to the other page, but appium server error: http code (500)

This is my code：

`
require 'appium_lib'
class Appbase
include Appium::Device
include Appium::Android
include Appium::Common
def start
caps = { caps: { platformName: 'Android',
appActivity: '.ui.LauncherUI',
appPackage: 'com.tencent.mm',
deviceName:'02157df27164db19',
chromeOptions: { androidProcess: 'com.tencent.mm:tools'}},
newCommandTimeout:'180',
appium_lib: { sauce_username: nil, sauce_access_key: nil,wait_timeout: 30,wait_interval: 1 },
}
@app = Appium::Driver.new(caps)
@touch = Appium::TouchAction.new
@app.start_driver
end
def weChat
begin
@touch.swipe(start_x:1400,start_y:300,end_x:300,end_y:300,duration:1000).perform
@touch.swipe(start_x:1400,start_y:300,end_x:300,end_y:300,duration:1000).perform
end
end
end
apps=Appbase.new
apps.start
apps.weChat

`

This is part of the log：

I think the wrong reason is the following request, the second request also bring the first time the parameters，resulting in server error（http code 500）

`

info: --> POST /wd/hub/session/b284bc83-8173-4235-8d27-a87f0bc7071a/touch/perform {"actions":[{"action":"press","options":{"x":1400,"y":300}},{"action":"wait","options":{"ms":1000}},{"action":"moveTo","options":{"x":300,"y":300}},{"action":"release"},{"action":"press","options":{"x":1400,"y":300}},{"action":"wait","options":{"ms":1000}},{"action":"moveTo","options":{"x":300,"y":300}},{"action":"release"}]}

Do i want to know the cause of the error? Thank you

How about the following commands?

def weChat
    begin
      Appium::TouchAction.new.swipe(start_x:1400,start_y:300,end_x:300,end_y:300,duration:1000).perform
      Appium::TouchAction.new.swipe(start_x:1400,start_y:300,end_x:300,end_y:300,duration:1000).perform
    end
  end
end

@touch stores all chained command.
.perfoem just requests stored commands to Appium server but don't clear the commands in @touch.

[KazuCocoa]

BTW, I consider if clearing stored commands when .perform is called in #511 .

Thank you!!! in fact, before asking questions, I have done so. Do not understand the principles of which, with the ruby ​​object-oriented syntax conflict.
