How To Retrieve Data From The Popup After Clickable Element Trigger With Webdriverwait In Selenium Python?

I need to scrape the image src from this popup. I have coded that but getting 'AttributeError: 'NoneType' object has no attribute 'findElements'. Here is the code. from selenium im

Solution 1:

Try using all the available element identifiers if one doesn't work, it worked with css_selector.

sizechart = driver.find_element_by_css_selector('#sizeImg > img').get_attribute("src")
print(sizechart)
