Answer 1

Check your "driver" parameter. Currently the error states, that a 'NoneType' object has no attribute 'find_element'.

_element_if_visible(driver.find_element(*locator)) ^^^^^^^^^^^^^^^^^^^ AttributeError: 'NoneType' object has no attribute 'find_element'

Looking at these lines of code we see the object is "driver".

driver.find_element(*locator)

So there is no valid driver provided.

With options provided it should work.

from selenium.webdriver.chrome.options import Options

options = Options()
options.page_load_strategy = 'normal'
driver = webdriver.Chrome(options=options)
