Fix FileNotFoundError

✅ Solution

FileNotFoundError in Polars usually arises when attempting to read or write files/directories that don't exist at the specified path. When reading, ensure the file path is correct and the file exists. When writing, create the necessary directories beforehand using `os.makedirs(path, exist_ok=True)` or enable automatic directory creation if the writing function supports it (e.g., `mkdir=True` in `sink_parquet`).
