I am trying to get Recaptcha parameters from selenium by executing a JavaScript code but somehow its returning 'Circular Reference Error'. I understand the meaning of the error but I don't know what is causing this problem in this case. This is the url of the site site-url I also tried lookin at other stackoverflow answers but they don't seem to help. when i ran it in chrome-console it runs fine.

driver.execute_script('return ___grecaptcha_cfg.clients[0]') #this one works
driver.execute_script('return ___grecaptcha_cfg.clients[100000]') #returns error

Error

Traceback (most recent call last):
