Hey @KkwwwkK! I'm here to help you with any bugs, questions, or contributions. Let's tackle this together!

The PermissionError: [Errno 13] Permission denied error you're encountering is likely due to restrictive file or directory permissions when dealing with temporary files. Here are some common causes and potential solutions:

1. File Permissions: Ensure that the temporary file has the correct permissions to be read and written. You can modify the permissions using os.chmod if necessary.

2. Directory Permissions: Ensure that the directory where the temporary file is being created has the correct permissions. The directory should allow read, write, and execute permissions.

3. Temporary File Handling: When creating temporary files, ensure that they are properly closed and not being accessed by another process. You can use tempfile.NamedTemporaryFile with delete=False to manage the file manually.

Here's an example of how you might handle temporary files with appropriate permissions:

import tempfile
import os

# Create a temporary file with appropriate permissions
with tempfile.NamedTemporaryFile(delete=False) as tmp_file:
    tmp_file_name = tmp_file.name

# Ensure the file has read and write permissions
os.chmod(tmp_file_name, 0o600)

# Use the temporary file
try:
    # Your code that uses the temporary file
    pass
finally:
    # Clean up the temporary file
    os.remove(tmp_file_name)

Additionally, ensure that the directory C:\\Users\\KW~1\\AppData\\Local\\Temp has the correct permissions for creating and accessing temporary files.

If the issue persists, it might be related to specific configurations or limitations within the DirectoryLoader or MongoDBAtlasVectorSearch classes. For example, the DirectoryLoader class raises errors if the specified directory does not exist or if the path is not a directory but a file ^[1]. Ensure that the path provided to DirectoryLoader is correct and accessible.

By addressing these potential causes, you should be able to resolve the PermissionError and successfully run your code.
