Scrapy-Selenium: Output contains 'None' value - selenium

Question

I am trying to execute this script using Scrapy-Selenium middleware to handle JavaScript. This script is not showing any error but provides 'None' output. I think I am missing something from this
followers = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.XPATH, "//a[#href='/goat/followers/']"))).click()
time.sleep(3)
particular line but I am unable to figure it out. What am I actually missing here? I am stuck at this point very badly.
