Unable to Get Parent Element Class Attribute, get_attribute() return None.

[Khald1998]

Problem Description

I'm using SeleniumBase in CDP mode and trying to get the class attribute of a parent element, but both the base element and its parent return None for get_attribute("class").

Code Example

def extract_response(sb):
    """Extract the response from chat bubbles"""
    try:
        logger.info("Waiting for response bubbles")
        base_selector = 'div[data-sentry-source-file="message-header.tsx"]'
        base_element = sb.cdp.find_element(base_selector, timeout=10)
        if not base_element:
            logger.error("Base element not found!")
        parent_element = base_element.get_parent()
        print(base_element.get_attribute("class"))  # Returns: None
        print(parent_element.get_attribute("class"))  # Returns: None
        print(type(parent_element))  # Returns: <class 'seleniumbase.undetected.cdp_driver.element.Element'>

Expected Behavior

• get_attribute("class") should return the CSS class string of the elements
• Parent element traversal should work consistently

Actual Behavior

• Both base_element.get_attribute("class") and parent_element.get_attribute("class") return None
• The elements definitely have class attributes when inspected in browser DevTools

Environment

• SeleniumBase Version: Latest
• Browser: Chrome (with UC mode)
• Mode: CDP mode
• Python Version: 3.x
• Operating System: Linux/Windows 10

Any guidance on proper attribute retrieval and DOM traversal would be greatly appreciated!

Use element.get_attribute("class_") to get the class.

Since "class" was already a reserved identifier, you have to use "class_" instead.
