fix: surface Langflow error and empty-response messages to users#10
Merged
Conversation
When a Langflow flow rejects a query or returns no content, the UI now displays an error message instead of silently showing nothing. This adds extract_error_from_sse_data() to detect Langflow SSE error events during streaming, and changes the empty-response path from a silent "done" to an explicit error event.
