GitHub connector indexing succeeds in logs but documents not available in "Manage Documents"

[ramezquitao]

Description:
I tried setting up the GitHub connector, but even though indexing tasks appear successful in the logs, the repository documents do not appear under Manage Documents, and querying always results in 0 related documents.

Steps to Reproduce:

1. Perform manual installation of SurfSense.
2. Create a GitHub personal access token with the following permissions:
   • Access to all repositories owned by me
   • Read access to code, issues, and metadata
   • No user permissions
3. Configure the GitHub connector in SurfSense with the token.
4. Index a repository.
5. After indexing:
   • Logs show successful connector_indexing_tasks.
   • On the connectors page, "Last Indexed" is initially updated.
   • After refreshing the page, "Last Indexed" reverts to "Never."
6. Go to Manage Documents → No documents listed, and queries return 0 results.

Expected Behavior:
After successful indexing, repository files should:

• Appear in Manage Documents
• Stay recorded in the connectors page (with correct "Last Indexed" date)
• Be retrievable when querying the repo

Actual Behavior:

• Logs report successful indexing.
• Manage Documents remains empty.
• Connectors page initially shows a "Last Indexed" date, but after refresh it reverts to "Never."
• Queries return "0 related documents."
