Python Code

from seleniumbase import Driver

driver = Driver(uc=True)

driver.open(URL)
element = driver.find_element("li[id^='marketItem']")
element_price = element.find_element(".rightCol")
print(element_price.text)
sleep(999)

I remember this working with undetected_chromedriver. But with Seleniumbase Driver I get the error:

selenium.common.exceptions.InvalidArgumentException: Message: invalid argument: invalid locator

Is there another way to find the element of inside of an element ? Thanks in advance
