Why won't this pass the challenge?

So I solved this challenge locally on two different ways, but both do not pass the online challenge. Since I am not sure why both solutions do not pass, I got stuck.

Solution 1:

import os
import re

# Filenames consist of a username (alphanumeric, 3-12 characters)
# and a date (four digit year, two digit month, two digit day),
# and an extension. They should end up in the format
# year-month-day-username.extension.

# Example: kennethlove2-2012-04-29.txt becomes 2012-04-29-kennethlove2.txt
date_regex = r'\d{4}-\d{2}-\d{2}'

def cleanup(path):
    filename, file_extension = os.path.splitext(path)
    date = re.search(date_regex, filename).group(0)
    username = filename.split('-')[0]
    new_name = f'{date}-{username}{file_extension}'
    os.rename(path, new_name)

solution 2

def cleanup(path):
    filename, file_extension = os.path.splitext(path)
    filename_lst = filename.split('-')
    return f'{filename_lst[1]}-{filename_lst[2]}-{filename_lst[3]}-{filename_lst[0]}{file_extension}'
consistency.py 
import os
import re

# Filenames consist of a username (alphanumeric, 3-12 characters)
# and a date (four digit year, two digit month, two digit day),
# and an extension. They should end up in the format
# year-month-day-username.extension.

# Example: kennethlove2-2012-04-29.txt becomes 2012-04-29-kennethlove2.txt
date_regex = r'\d{4}-\d{2}-\d{2}'

def cleanup(path):
    filename, file_extension = os.path.splitext(path)
    date = re.search(date_regex, filename).group(0)
    username = filename.split('-')[0]
    new_name = f'{date}-{username}{file_extension}'
    os.rename(path, new_name)

In the challenge description, it says This function should take a string which will be a path to a local directory. but your code looks like it takes in a path to a file instead of a path to a folder.

You were right, thank you. Completely overlooked that
