TimeoutError on your example

[gregorleban]

OS: Windows 11
Python: 3.11.5

I'm running the current selenium-driverless version and on the example code:

from selenium_driverless import webdriver
from selenium_driverless.types.by import By
import asyncio


async def main():
    options = webdriver.ChromeOptions()
    async with webdriver.Chrome(options=options) as driver:
        await driver.get('http://nowsecure.nl#relax', wait_load=True)
        await driver.sleep(0.5)
        await driver.wait_for_cdp("Page.domContentEventFired", timeout=15)
        
        # wait 10s for elem to exist
        elem = await driver.find_element(By.XPATH, '/html/body/div[2]/div/main/p[2]/a', timeout=10)
        await elem.click(move_to=True)

        alert = await driver.switch_to.alert
        print(alert.text)
        await alert.accept()

        print(await driver.title)


asyncio.run(main())

I get the exception:

Traceback (most recent call last):
  File "e:\Development\Anaconda3\Lib\asyncio\tasks.py", line 490, in wait_for
    return fut.result()
           ^^^^^^^^^^^^

    return await self._fut
           ^^^^^^^^^^^^^^^
asyncio.exceptions.CancelledError

The above exception was the direct cause of the following exception:

  File "e:\Development\Anaconda3\Lib\asyncio\tasks.py", line 492, in wait_for
    raise exceptions.TimeoutError() from exc
TimeoutError

I also get the TimeoutError on all actions where I want to either find element or even call a .get() method to load another page. Any idea what is going on?

pip freeze returns (for some relevant packages only):

asyncio==3.4.3
requests==2.32.3
selenium==4.22.0
selenium-stealth==1.0.6
selenium_driverless==1.9.4

Hi,

thank you for your reply. Unfortunately it didn't solve the issue and I'm still having the same problem.

I tried running the Windows Sandbox (without Chrome, python, ...) and installed current Chrome, and tried two settings:

• installing anaconda with python 3.11.5 + selenium-driverless (no other packages were installed).
• installing latest anaconda with python 3.13.5 + selenium-driverless (no other packages were installed).

In both cases I ran the code that I've sent above and always still get the same exception:

C:\script>python test.py
Traceback (most recent call last):
  File "C:\ProgramData\anaconda3\Lib\asyncio\tasks.py", line 507, in wait_for
    return await fut

    return await self._fut
           ^^^^^^^^^^^^^^^
asyncio.exceptions.CancelledError

The above exception was the direct cause of the following exception:

Any idea what else could I try?

So the problem is you’ve got asyncio==3.4.3 installed via pip and it’s messing with python 3.11.5. That version of asyncio is ancient and was meant for old python versions. It’s screwing up the built-in asyncio which is why your selenium-driverless script is acting up. Just uninstall it with pip uninstall asyncio and let python use the native asyncio. Once you do that your script should run fine and wait_for_cdp() wont throw timeout/cancelled errors anymore. Also I recommend you to doublecheck with asyncio.file to make sure it’s loading the right one

This is complete nonsense.

@gregorleban The website has changed and code isn't up to date anymore.
You can likely just comment the line

await driver.wait_for_cdp("Page.domContentEventFired", timeout=15)

to resolve this issue.

[gregorleban]

@kaliiiiiiiiii thank you for your response.

I've commented out the code, but the code still fails.

I've also tried simply loading another page like:

await driver.get("https://www.nytimes.com/", wait_load=True)
await driver.find_element(By.CSS_SELECTOR, '.fides-overlay-modal-link-shown')

and I get the timeout exception:

 File "C:\script\test.py", line 18, in main
    await (await driver.find_element(By.CSS_SELECTOR, '#fides-button-group .fides-accept-all-button')).click()
  File "c:\ProgramData\anaconda3\Lib\site-packages\selenium_driverless\types\webelement.py", line 566, in click
    raise asyncio.TimeoutError(f"Couldn't compute element location within {visible_timeout} seconds")
TimeoutError: Couldn't compute element location within 10 seconds

This happens in the windows sandbox, with clean chrome install, python 3.13.5 + selenium-driverless. No other extra packages installed.

and I get the timeout exception:

 File "C:\script\test.py", line 18, in main
    await (await driver.find_element(By.CSS_SELECTOR, '#fides-button-group .fides-accept-all-button')).click()
  File "c:\ProgramData\anaconda3\Lib\site-packages\selenium_driverless\types\webelement.py", line 566, in click
    raise asyncio.TimeoutError(f"Couldn't compute element location within {visible_timeout} seconds")
TimeoutError: Couldn't compute element location within 10 seconds

Again, this is because the target page is outdated.
Technically not a bug, just some outdated documentation in here:)

@kaliiiiiiiiii: I'm sorry, but I really don't understand what to do to fix it. I've checked the code and it seems that the find_element method is still there and has the same signature so it's not clear how can I correctly execute the code:

await driver.get("https://www.nytimes.com/", wait_load=True)
await driver.find_element(By.CSS_SELECTOR, '.fides-overlay-modal-link-shown')

and I get the timeout exception:

 File "C:\script\test.py", line 18, in main
    await (await driver.find_element(By.CSS_SELECTOR, '#fides-button-group .fides-accept-all-button')).click()
  File "c:\ProgramData\anaconda3\Lib\site-packages\selenium_driverless\types\webelement.py", line 566, in click
    raise asyncio.TimeoutError(f"Couldn't compute element location within {visible_timeout} seconds")
TimeoutError: Couldn't compute element location within 10 seconds

Again, this is because the target page is outdated. Technically not a bug, just some outdated documentation in here:)

*correction
This is usually when the element you're trying to click on isn't visible
