The error "list index out of range" is likely happening because you are trying to access an index of a list that is not present. Here are a few ways to fix this:

1. Check if the list is empty or not before accessing its elements. If the list is empty, handle the case appropriately.
2. Use the try-except block to handle the error. In the except block, you can either return an error message or use a default value.
3. Increase the size of the list.

Without the complete traceback, it's difficult to determine exactly where the error is occurring and what needs to be done to fix it. You may need to do some debugging to find the exact line of code that is causing the problem.

Here's a fixed version that should handle the "list index out of range" error:

def canGoForward(soup):
    try:
        pagination = soup.find('div', class_='Zebra_Pagination')
        if pagination is not None:
            next_page_list = pagination.find_all('li')
            if len(next_page_list) > 0:
                next_page = next_page_list[-1]
                if next_page.text == 'Next':
                    return next_page.a['href'] != 'javascript:void(0)'
    except Exception:
        return False
    return False

This version adds a try-except block to handle any exceptions that may occur, and also adds a check to see if next_page_list has any items before accessing the last item. If there are no items in next_page_list, the function returns False

list index out of range.

The "list index out of range" error occurs because the "next_page_list" doesn't have any items and you are trying to access the last item of an empty list. You can resolve this by checking if "next_page_list" has any items before accessing its last item.
Here's a modified version of the code that should handle this error:

def canGoForward(soup):
    try:
        pagination = soup.find('div', class_='Zebra_Pagination')
        if pagination is not None:
            next_page_list = pagination.find_all('li')
            if len(next_page_list) > 0:
                next_page = next_page_list[-1]
                if next_page.text == 'Next':
                    return next_page.a['href'] != 'javascript:void(0)'
    except Exception:
        return False
    return False
