'WebDriver' object has no attribute 'w3c' when running execute_script

Issues/Bugs
1

Hello, yesterday I update to the latest appium-python client and immediately got test failures when running:

self.driver.execute_script(“mobile: scroll”, {“direction”: “down”, “text”: user})

The error is below. Any help is appreciated.

def execute_script(self, script, *args):
“”"
Synchronously Executes JavaScript in the current window/frame.

    :Args:
     - script: The JavaScript to execute.
     - \*args: Any applicable arguments for your JavaScript.

    :Usage:
        driver.execute_script('return document.title;')
    """
    converted_args = list(args)
    command = None

  if self.w3c:

E AttributeError: ‘WebDriver’ object has no attribute ‘w3c’

I also tried the following code using the w3c actions suggested on the python-client git, but I still got the same error. This time is when getting window_size()

Code:
def scroll_down(self):
window = self.__appium_driver.get_window_size()
actions = ActionBuilder(self.__appium_driver)
actions.pointer_action.move_to_location(window.width / 2, window.height * 8 / 10)
actions.pointer_action.pointer_down()
actions.pointer_action.move_to_location(window.width / 2, window.height / 10)
actions.pointer_action.release()
actions.perform()

Error:
def get_window_size(self, windowHandle=‘current’):
“”"
Gets the width and height of the current window.

    :Usage:
        driver.get_window_size()
    """
    command = Command.GET_WINDOW_SIZE

  if self.w3c:

E AttributeError: ‘WebDriver’ object has no attribute ‘w3c’

Here is the documentation for the Python Client:

There is a section on migration from v1 to v2 that states:

Deprecated
MultiAction and TouchAction are deprecated. Please use W3C WebDriver actions.
e.g.
appium/webdriver/extensions/action_helpers.py
/documentation/webdriver/actions_api/mouse/
https://www.youtube.com/watch?v=oAJ7jwMNFVU
Appium Pro: iOS-Specific Touch Action Methods
Appium Pro: Automating Complex Gestures with the W3C Actions API
launch_app, close_app and reset are deprecated. Please read issues#15807 for more details

Does that help?

Thank you wreed. I did read that and one of the links there shows that execute_script should still work(?)
https://appiumpro.com/editions/30-ios-specific-touch-action-methods

My last post also shows the actionbuilder method snippet for scrolling, but I’m still using get_window_size() and that gives me the error.

I would like to find a way to do this without having to back to v1.

Yeah, this is confusing to me too. I’m not a Python guy. I’m looking at the client repo tests:

Seems like they are using ‘self.execute_script’ instead of ‘self.driver.execute_script’. I probably don’t understand the difference though.

I also wonder if in your first script you might try: if self.driver.w3c. But I’m not sure about this.

I assume this might be an issue with the selenium’s python client. The one in Appium does not have such attribute defined nor override any of the mentioned methods.

Thank you both. I am going to crosspost this to the python-client git and see if it is a bug on their end

I assume this issue can be fixed by updating the selenium to 4.0.0, I had an issue using driver.get_window_size() & the update fixed it
