getSize method does not work and throws an server internal exception

[mukund-billa]

Hello,

I have observed certain issues when i uploaded my appium testng scripts to AWS device farm. Whenever the driver.manage().window().getSize() method is executed, the AWS gets the unknown server-side error. And also in device farm, whenever i tried to get the location of an element, it gets a null pointer exception.

Appium: 1.6.5
IOS : 10.3.2

Kindly provide any suggestions/workaround.

Thanks,
Mukund

Hello Mukund,

I'm currently facing the same issue with AWS device farm. It is also present for getLocation() call, as probably both calls share some part of implementation.
After further research on this, I've found out that reason behind it is miscommunication between Appium on server side and the device. It reports that iOS native class is not key-value coding compliant for key “wdWidth”.
Also I've tried working around it by using getAttribute("rect") method on a WebElement, which returns a string from which both location and size values can be parsed. Although it works on both AWS and in local runs, there is a difference in format it returns. Here are the examples:

Local: {x=0, width=375, y=64, height=603}
AWS: {size={width=374, height=603}, origin={x=0, y=64}}

So when parsing the components out, you should find out which is returned format and adapt to it.

Good luck,
Zeljko

Hey Zeljko,
Thanks a ton for your workaround. Let me do some code tweaks based on your suggestion and see if that resolves the issue.

Also, the is there any other way where we can get the size of the device window. As of now, i am unable to get the size of the device window in AWS device farm using getSize method of Window. Locally, the methods are working fine the issue is always crop up whenever the code runs in AWS Device farm platform.

Hi Mukund,
I forgot to mention that getAttribute("rect") would work only on iOS. Didn't take Android into account, as your first post was about the iOS issue.
But anyways, for Android getSize() and getLocation() is working fine, so there is no need for a workaround there.
Best,
Zeljko

Thanks for the quick reply zeljko, I tried getAttribute("rect") for IOS and its working fine, i will parse it with respect to AWS data.If there are any suggestions for getSize() of window with IOS will be helpful.

@mukund-billa : Is this still an open issue ?

[mukund-billa]

the issue is resolved but still the swipe is not functioning in AWS device farm on IOS devices.
Do we have any other suggestions/workaround on swipe functionality on IOS devices in AWS device farm.

@mukund-billa We recently fixed some issues with WebDriverAgent on our side. Can you please verify if you are still seeing issues on Appium 1.6.5?

[nikhil-dabhade]

Is the issue discussed here related to the appium sample tests on this repository ?

[mukund-billa]

Its in general issue which is being observed in AWS Device Farm for IOS Devices.
