Python - invalid argument: can't kill an exited process

[brunoapcd]

Hi guys, I am trying to use Geckodriver in my Python application hosted on Heroku and I'm getting the following exception:

"invalid argument: can't kill an exited process"

My code:
from selenium.webdriver.firefox.options import Options

options = Options()
options.headless = True
options.binary_location = os.environ.get("FIREFOX_BIN")
driver = webdriver.Firefox(options=options, executable_path=os.environ.get("GECKODRIVER_PATH"))

driver.get("https://my-url")

Any ideas? I already installed the buildpacks and set all the server variables.

Having the same issue here. Seems like firefox won't start up at all:

> ~/vendor/firefox $ ./firefox -h

XPCOMGlueLoad error for file /app/vendor/firefox/libxul.so:
libXt.so.6: cannot open shared object file: No such file or directory
Couldn't load XPCOM.

Same issue here as well.

@brunoapcd, with the limited code and logs that you've posted, it's hard for me to guide you. Would appreciate it if you could post more detailed debug logs.

@adamb70 and @kingkong-cmd, XPCOMGlueLoad error hints that the error originates from firefox, which is out of the scope of this buildpack as explained in this issue #6
