问题
I have run somel iOS Appium tests (Java TestNG) on iOS devices for my app.
Some tests don't even install the app, on six or seven out of 22 devices. All with the exact same error about not creating a session:
Trying to execute simple Appium Driver
Failed to invoke configuration method scenarios.ScreenshotsAppiumTest.setUp:
It is impossible to create a new session because
'createSession' which takes HttpClient,
InputStream and long was not found or it is not accessible
The test works and passes on all my devices and almost all other devices on AWS Device Farm. In those devices where it fails, it does nothing. It doesn't install the app.
I have no idea how to debug this test or why they are not running. Google doesn't help.
I am positive the test works, since it works on other devices.
I'd like to know how to debug or try to solve this error. What are the steps to debug Appium not installing the app on AWS Device Farm? What can I do? Is there any command to execute to get more logs? Anything? I have asked this same question on AWS Forum without any luck.... Thanks.
The error I have in the logs this one:

Update. I have found devices with this issue. It looks like it happens on
Apple iPad 2 iOS version 9
Apple iPad Air 2 iOS version 9
Apple iPad Mini 1st Gen iOS version 9
Apple iPad Mini 3
Apple iPad Pro 9.7" iOS version 10
Apple iPhone 5s iOS version 9
Apple iPhone 7 Plus iOS version 10
On versions 9 of iOS. I am not worring too much about it because it looks like a version issue. I accept my own answer until future research and checking other versions.
For future reference here's the log of one device:
