# Add path validation to DirectoryLoader This PR introduces a minor adjustment to the DirectoryLoader by adding validation for the path argument. Previously, if the provided path didn't exist or wasn't a directory, DirectoryLoader would return an empty document list due to the behavior of the `glob` method. This could potentially cause confusion for users, as they might expect a file-loading error instead. So, I've added two validations to the load method of the DirectoryLoader: - Raise a FileNotFoundError if the provided path does not exist - Raise a ValueError if the provided path is not a directory Due to the relatively small scope of these changes, a new issue was not created. ## Before submitting <!-- If you're adding a new integration, please include: 1. a test for the integration - favor unit tests that does not rely on network access. 2. an example notebook showing its use See contribution guidelines for more information on how to write tests, lint etc: https://github.com/hwchase17/langchain/blob/master/.github/CONTRIBUTING.md --> ## Who can review?
