Warning issued on program exit after driver.quit()

[j-foreman]

I run the following script:

import logging
import undetected_chromedriver as uc

logging.basicConfig(level=logging.DEBUG)

driver = uc.Chrome()
input("return to continue")
driver.quit()
input("return to continue")

and I get the following output (note the warnings in the last part):

If I don't run driver.quit() and just let the program exit I don't see the warnings. This seems to happen because when the program exits the quit() method of selenium WebDriver is called here but the browser is already closed by the earlier driver.quit() method in my script.

i'm having the same problem here

[Altimis]

I had the same problem and I used driver.close() instead (only).

Quick fix, but I'm not sure if it's correct. I just overridden the del method. Correct me if I am wrong

class Chrome(uc.Chrome):

    def __del__(self):
        self.quit()
