fix: enhance error handling for document processing and add OCR requirement check for image files by ricofurtado · Pull Request #1859 · langflow-ai/openrag

ricofurtado · 2026-06-12T15:15:26Z

Supported File Types by Ingestion Path

There are currently two different supported file type lists depending on how content is ingested into OpenRAG.

Direct Upload (Frontend File Picker)

Defined in knowledge-dropdown.tsx (lines 60–76).

Category	Extensions
Documents	`.txt`, `.md`, `.pdf`, `.docx`, `.html`, `.htm`, `.adoc`, `.asciidoc`, `.asc`
Spreadsheets	`.csv`, `.xlsx`
Presentations	`.pptx`

Connector Ingestion (Backend Validator)

Defined in processors.py (lines 645–668).

Includes all file types supported by Direct Upload, plus additional Office formats, XHTML, and image formats.

Category	Extensions
Documents	`.txt`, `.md`, `.pdf`, `.docx`, `.html`, `.htm`, `.adoc`, `.asciidoc`, `.asc`
Additional Office Documents	`.dotx`, `.dotm`, `.docm`
Spreadsheets	`.csv`, `.xlsx`, `.xls`
Presentations	`.pptx`, `.potx`, `.ppsx`, `.pptm`, `.potm`, `.ppsm`
Web Documents	`.xhtml`
Images	`.jpg`, `.jpeg`, `.png`, `.tiff`, `.bmp`, `.webp`

Root Cause of the Reported Defect

The image formats (.jpg, .jpeg, .png, .tiff, .bmp, .webp) are the source of the reported issue.

What Happens

The connector ingestion validator accepts image files based on extension.
The files are sent through the ingestion pipeline.
Images only produce extractable text when Docling OCR is enabled.
When OCR is disabled, no text content is extracted.
No chunks are generated for indexing.
The updated ingestion logic now correctly marks these files as Failed rather than Active.

Existing Frontend Limitation

The frontend intentionally excludes several file types that are accepted by connector ingestion.

A TODO comment in knowledge-dropdown.tsx (line 57) states:

Re-add other MIME/extension groups (images, xlsx/xls/ppt, rtf/odt, etc.) once ingestion is verified end-to-end in Langflow.

This indicates that support for images and additional document types was intentionally withheld from the file picker until end-to-end ingestion behavior was fully validated.

Gap Between Frontend and Connector Validation

Area	Images Allowed?
Frontend File Picker	❌ No
Connector Ingestion Validator	✅ Yes

This inconsistency allows image files to be ingested through connectors while bypassing the frontend restrictions, creating the gap that exposed the bug.

Summary by CodeRabbit

Bug Fixes

Improved validation of document processing results to ensure failures are correctly detected and reported when content is not properly indexed
Enhanced error messages for image files to provide specific guidance when OCR processing is required for content extraction
