TL;DR

Modify the _process_attachments() method to pass the cached_path to MessageEvent.media_urls or introduce a new field like document_urls to handle file attachments.

Guidance

• Identify the lines in adapter.py where cached_path is obtained and modify the code to append this path to MessageEvent.media_urls instead of just the filename text.
• Consider introducing a new field document_urls in MessageEvent to handle file attachments separately from images, to avoid potential conflicts or limitations.
• Verify that the media_urls or new field is correctly populated with the file path by logging or debugging the MessageEvent object after modification.
• Ensure that the agent can access and handle the file attachments correctly once the file path is passed to MessageEvent.

Example

# Modified code in _process_attachments():
else:
    cached_path = await self._download_and_cache(url, ct)
    if cached_path:
        other_attachments.append(cached_path)  # ← append the actual file path
        # or introduce a new field like document_urls
        document_urls.append(cached_path)

Notes

The suggested fix assumes that the media_urls field can handle both image and file attachments. If there are specific requirements or limitations for handling different types of attachments, introducing a new field like document_urls might be a better approach.

Recommendation

Apply workaround by modifying the _process_attachments() method to pass the cached_path to MessageEvent.media_urls or introduce a new field like document_urls, as this directly addresses the identified issue and allows for a straightforward verification of the fix.
