[Python] Logs not being written of parent directory included in filename

I have a function that creates a logger that prints and exports logs to a file:

# logger.py

import os
import pathlib
import logging
from dates import get_current_date


def get_logger(name=__name__, level=logging.DEBUG):
logger = logging.getLogger(name)
logger.setLevel(level)

# Get current date to append to file name
formatted_date = get_current_date()
logfile = f"{name}_{formatted_date}.log"
logfile_output = f"./{os.path.join('Logs', logfile)}"
os.makedirs(os.path.dirname(logfile_output), exist_ok=True)

# Create a file handler with detailed formatting for log output
file_handler = logging.FileHandler(logfile_output , mode="a")
fformatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s : %(message)s')
file_handler.setFormatter(fformatter)

# Create a stream handler with simple formatting for cell output
stream_handler = logging.StreamHandler()
sformatter = logging.Formatter('%(message)s')
stream_handler.setFormatter(sformatter)

# Add the handlers to the logger
logger.addHandler(file_handler)
logger.addHandler(stream_handler)

logger.info('Logger initiated. Logs will be written to %s', logfile_output)

return logger


# notebook
from logger import get_logger

name = 'dev'
logger = get_logger(name)

logger.info('this is a log')

%sh
ls Logs # returns nothing
ls Logs/ # returns nothing


The idea was to either write the .log files to a Logs folder in the root project directory or same directory as the notebook. The issue is it won't write anything if I include the Logs/ in the logfile_output, but works if I just write it as logfile with a directory (eg logfile.log). I've tried different paths and ways of writing the a Logs folder but nothing happens.
