1 year ago According to these versions our core web-driver downloader should detect the right version and download it.
We can test the behaviour by evaluating in a robot ran in the cloud code like:
from webdriver_manager.chrome import ChromeDriverManager as CDM; print(CDM().driver.get_driver_download_url())which should print an URL like:
https://chromedriver.storage.googleapis.com/105.0.5195.52/chromedriver_....zipI confirm the issue, which looks to come from our outdated Chrome browser found in the Cloud Worker.
Context: When the default chromedriver available in PATH is used everything works fine, but if a suitable web-driver is attempted to be downloaded, then we run into problems.
Problem: There's no suitable web-driver found to be downloaded for Chrome version 105.0.5195.102: Incompatible release of chromedriver (version 105.0.5195.102) detected in PATH: /usr/bin/chromedriver
Result: Both our web-driver core manager and the Selenium built-in Manager fail to download a version that will satisfy the current version of the Chrome browser, thus it will fail to start. (see Process)
Solution: Patching our own web-driver core manager in such a way it will try to download the closest version found. (instead of the latest in case of mismatch)
@kariharju Do you think we can do ourselves a favor and provide the latest Chrome (or a version that has a web-driver available)? (the current browser dates back from Aug 30, 2022)

1 year ago We concluded that the real problem was actually trying to get the Chromium browser version in a Chrome way, which led to no version being discovered at all, which led to downloading the latest chromedriver, which of course is incompatible with the current version of Chromium we have in the container.
The fix was to detect when we have Chromium only in the system and go that route with the web-driver management instead, if by any non-recommended reason downloading is explicitly enabled.
