Mismatch of Firefox & Geckodriver versions? #10

Closed firozzer closed 4 years ago

firozzer commented 4 years ago

Hi, i added this buildpack to heroku but keep getting this error:

selenium.common.exceptions.WebDriverException: Message: invalid argument: can't kill an exited process

After searching about it, it seems this is caused by incompatible Firefox & Geckodriver versions. Any help on how to solve this error? Thank you.

I keep getting this error when trying to create the Selenium Webdriver object:

File "sendSWA.py", line 29, in sendScheduledMessage driver = webdriver.Firefox(firefox_profile=fp, options=options, executable_path=os.environ.get("GECKODRIVER_PATH"),firefox_binary=os.environ.get("FIREFOX_BIN")) File "/app/.heroku/python/lib/python3.6/site-packages/selenium/webdriver/firefox/webdriver.py", line 174, in __init__ keep_alive=True) File "/app/.heroku/python/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 157, in __init__ self.start_session(capabilities, browser_profile) File "/app/.heroku/python/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 252, in start_session response = self.execute(Command.NEW_SESSION, parameters) File "/app/.heroku/python/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute self.error_handler.check_response(response) File "/app/.heroku/python/lib/python3.6/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.WebDriverException: Message: invalid argument: can't kill an exited process

Any help please?

@XtremePwnership

Error invalid argument: can't kill an exited process originates when the selenium is unable to spawn a new instance of the web driver.

Incompatibility between Firefox and Geckodriver could be a probable reason as well.

I've hardcoded the stable versions for Firefox and Geckodriver in the code. However, if those version doesn't seem to work out for you, feel free to fork the repo and update your codebase with desired versions for Firefox and Geckodriver.
