[🐛 Bug]: AttributeError: 'AppiumConnection' object has no attribute '_ca_certs'

[Trouler]

What happened?

We are automating actions on both an Android phone on Windows, and on a Iphone on macOS. The macOS automation stopped working in the latest update, with this error:
AttributeError: 'AppiumConnection' object has no attribute '_ca_certs'

It's happening when attempting to initiate a Remote WebDriver

How can we reproduce the issue?

Will be removing quite a lot of internal code here, but hopefully relevant code is enough to figure out why it happens.
---------------------------------------------------------

from appium.webdriver import Remote
from appium.options.ios import XCUITestOptions
from appium.webdriver.appium_service import AppiumService

options = XCUITestOptions()
options.set_capability("newCommandTimeout", 3000)
options.device_name = "SECRET"
options.platform_version = "16.4"
options.automation_name = "XCUITest"
options.show_xcode_log = True
options.xcode_org_id = "SECRET"
options.xcode_signing_id = "iPhone Developer"
options.udid = "SECRET"

host = "localhost"
port = "4723"

appium_service = AppiumService()
appium_service.start(args=["--address", host, "--port", port], main_script="/usr/local/bin/appium")
assert appium_service.is_running
driver = Remote(f"http://{host}:{port}", options=options)

Relevant log output

self.driver = Remote(f"http://{appium_host}:{appium_port}", options=options)

First, can you try to pin selenium python to version 4.25.0?

[VietND96]

Hi @KazuCocoa, could you please review this can be resolved once this PR appium/python-client#1054 is implemented on top of 4.26.0?

[Trouler]

First, can you try to pin selenium python to version 4.25.0?

Yes sorry, I should probably have added that in the issue description. We are currently working around it by pinning, so 4.25.0 is working fine.

[KazuCocoa]

Np, I'll release a new Python client with up to 4.25.0 anyway. 4.26.0+ will be a new version with planned modifications in appium/python-client#1054

This was not expected one as not it was in #14587 though. For me, maybe #14692 will bring more impact for Appium users who use Appium on slow spec CI machine. I'll update appium python client's README as well for 4.26+ selenium bindings update in our project.

[VietND96]

I added back those 2 attrs in class RemoteConnection. It will probably work in patch 4.26.1

[KazuCocoa]

Sure. I'll release a new Python client with up to 4.25 anyway since we need to prepare some documentation like request timeout thing with a new version update based on 4.26.
