Troubleshooting

Common Issues

Solutions to the most frequently encountered problems.

A document shows "Error" status

Click the document to see the error message. Common causes: the file is password-protected, the file format is not supported, or the file is corrupted. Try re-exporting the original and re-uploading.

Fields are extracting the wrong value

Add a custom AI instruction to the field explaining what value to extract. Be specific — for example "Extract the invoice subtotal before tax, not the total including tax." You can also try renaming the field to a clearer name.

A field is always empty

Check that the field's AI toggle is enabled. If it is, the information may not be present in the document, or the AI needs a clearer instruction to find it. Try adding a field instruction with an example value.

Uploaded document is not appearing in the inbox

Refresh the page. If the document still doesn't appear, check that the file format is supported (PDF, PNG, JPG, TIFF, XLSX). Files over 50MB may be rejected — check the file size.

Processing is taking a long time

Most documents process in under 30 seconds. Large PDFs (50+ pages) or documents with Advanced Reasoning enabled may take 1–2 minutes. If processing is stuck for over 5 minutes, try re-uploading.

Table data is missing or incomplete

Enable Advanced Table Extraction in Parser Settings. If the table spans multiple pages, ensure the page limit setting includes all relevant pages. For complex tables, adding column descriptions in field instructions can help.

CSV export is missing some documents

The CSV export only includes documents visible in the current view. Clear all active filters and try exporting again.

Still stuck?

Contact support with your parser ID and the document ID in question. You can find both in the URL when viewing a document.
