Check File Format and Encoding
- Ensure the PDF is not scanned (image-based) —Autopilot needs text-based PDFs for proper indexing.
- Try uploading a simple text-only PDF as a test — if it works, the issue may be with the specific PDF you uploaded.
Check File Permissions
- Ensure your storage bucket is
- In the same folder where Autopilot is being used
- You have read access to it
- Try downloading the file manually from the bucket to ensure access is working.
Limit File Size
- ECS indexing may fail if the file is too large or has too many pages.
- As a test, upload a small PDF (e.g., 1–2 pages) and add it to Context Grounding. If that works, your original file might be too large or complex.
Avoid Special Characters in File Name
- File names with characters like
#,+,%, or spaces can cause issues with URL encoding. - Rename the file to something simple like
invoice.pdfand re-upload.
Clear and Reconfigure Context Grounding
- Remove the current grounding config.
- Restart Autopilot.
- Re-add the index only after verifying the file format and size.
