admin	f32a21f87a	Merge pull request 'Revert SSE streaming for PDF import, use synchronous flow' (#11 ) from revert/remove-sse-streaming into main Reviewed-on: #11	2026-03-14 17:13:00 +00:00
vakabunga	8b57dd987e	Revert SSE streaming for PDF import, use synchronous flow SSE streaming added unnecessary complexity and latency due to buffering issues across Node.js event loop, Nginx proxy, and Docker layers. Reverted to a simple synchronous request/response for PDF conversion. Kept extractLlmErrorMessage for user-friendly LLM errors, lazy-loaded pdf-parse, and extended Nginx timeout.	2026-03-14 20:12:27 +03:00
