📄 Description

Description

Fixes #18973

This PR resolves two critical bugs preventing Open WebUI from starting:

  1. Firecrawl Import Error: Updates imports to use FirecrawlApp instead of Firecrawl
  2. Socket.IO CORS Warning: Properly handles wildcard CORS origins for Socket.IO

Changes Made

Firecrawl Import Fix

  • Updated import from Firecrawl to FirecrawlApp in backend/open_webui/retrieval/web/utils.py
  • Updated import from Firecrawl to FirecrawlApp in backend/open_webui/retrieval/web/firecrawl.py
  • Updated all class instantiations to use FirecrawlApp

Root Cause: The firecrawl package (v1.12.0+) changed its exported class from Firecrawl to FirecrawlApp, causing ImportError on startup.

Socket.IO CORS Fix

  • Modified backend/open_webui/socket/main.py to properly handle wildcard CORS origins
  • Added SOCKETIO_CORS_ORIGINS variable to convert ["*"] to "*" for Socket.IO compatibility

Root Cause: Socket.IO requires wildcard CORS as string "*", not list ["*"], causing origin validation warnings.
