Document Processing Issues

This guide helps you resolve problems with uploading, processing, and indexing documents in knowledge bases.

Upload failures

File upload doesn’t start

  • Check file size — The file may exceed the maximum allowed size for your plan
  • Check file format — Ensure the file is in a supported format (PDF, DOCX, XLSX, TXT, PPTX, CSV)
  • Browser issues — Try a different browser or clear your browser cache
  • Network issues — Check your internet connection; large files need a stable connection

Upload starts but fails midway

  • Network instability — A network interruption during upload. Try again with a stable connection.
  • File corruption — The file may be damaged. Try opening it locally to verify, then re-upload.
  • Server timeout — Very large files may time out. Try splitting the document into smaller files.

Indexing issues

Document stuck in “Processing”

If a document stays in “Processing” status for an unusually long time:
  1. Wait — Large documents or bulk uploads may take longer. Allow up to 30 minutes for large batches.
  2. Check the queue — If many documents were uploaded simultaneously, they’re processed sequentially.
  3. Retry — Delete the document and upload it again.
  4. Contact support — If it’s still stuck after retrying, there may be a backend issue.

Document status is “Failed”

Common reasons for processing failures:
CauseSolution
Unsupported formatConvert to a supported format (PDF, DOCX, etc.)
Corrupted fileRepair or re-export the file from its source application
Password-protected PDFRemove password protection before uploading
Encrypted documentDecrypt the document before uploading
Empty fileEnsure the file has actual content
Unreadable scanFor scanned PDFs, ensure the scan quality is adequate for OCR
If documents show “Indexed” status but the agent can’t find them:
  1. Wait a moment — There may be a brief delay between indexing and searchability
  2. Check your query — Try different phrasings; the content may not match your exact wording
  3. Check access control — You may not have access to the knowledge base
  4. Verify content — Open the original document and confirm the information you’re looking for is actually in the text (not just in images or headers)

SharePoint / Google Drive sync issues

Sync not picking up new files

  • Verify the files are in the folder/library that was selected during datasource configuration
  • For auto-sync, wait for the next sync cycle
  • Trigger a manual sync from the datasource settings
  • Verify the connection credentials haven’t expired (re-authorize if needed)

Previously synced files missing

  • The file may have been moved or deleted in the source system
  • The connection may need re-authorization
  • Check the datasource sync status for error messages
