- Changed progress callback from "execution_complete" to "workflow_graph_finished" to provide intermediate updates.
- Updated documentation to clarify the distinction between "workflow_graph_finished" and "execution_complete".
- Adjusted frontend API handling to accommodate new event structure and ensure proper result serialization.
Root cause: FastAPI matches routes in definition order. The /{prompt_id}
catch-all at line 257 was intercepting /execute-stream requests before
the specific route handler could match.
Fix: Moved execute-stream definition (with section header + imports)
to line 257, before the catch-all route (now at line 414).
This resolves the 'Connection to server lost' error in SSE streaming.
- /execute-stream now at line 260 (was 1448)
- /{prompt_id} now at line 410 (was 257)
- FastAPI will now match /execute-stream correctly
- Fixes 'Connection to server lost' error in analysis page
ROOT CAUSE FOUND:
FastAPI matches routes in ORDER. The catch-all route /{prompt_id} at line 257
matches /execute-stream BEFORE the specific route at line 1448 can match.
Result: /api/prompts/execute-stream gets routed to get_prompt() which tries
to parse 'execute-stream' as a UUID, causing the error we've been seeing.
SOLUTION: Move /execute-stream route definition to BEFORE line 257 (before /{prompt_id})
This explains why require_auth_flexible was never called - the wrong endpoint
was being invoked entirely.
Root Cause:
- FastAPI cannot use same parameter name in endpoint and dependency
- Query param 'token' conflicted between endpoint and require_auth_flexible
- FastAPI cached dependency signatures at startup
Solution:
- Renamed to 'ssetoken' in require_auth_flexible (backend/auth.py)
- Updated frontend to use ssetoken (frontend/src/utils/api.js)
- Removed debug logging
- Added test endpoint /test-ssetoken
Testing:
✅ Header auth: X-Auth-Token works
✅ Query auth: ?ssetoken=XXX works
✅ SSE streaming: Ready for testing
Note: Required full rebuild, not just restart

Root Cause Analysis:
- FastAPI cannot distinguish between endpoint Query params and Dependency Query params
- When endpoint has Query(...), dependency Query(default=None, name='token') is ignored
- Token went to endpoint, not to require_auth_flexible
Solution:
- Renamed internal parameter to auth_token with alias='token'
- Now FastAPI correctly routes ?token=XXX to the dependency
- Uses Query(default=None, alias='token') to maintain API compatibility
Testing:
- Header auth: Works (X-Auth-Token)
- Query auth: Now works (?token=XXX)

Backend:
- prompts.py: @router.post → @router.get für /execute-stream
- EventSource unterstützt nur GET-Requests
- modules/timeframes nutzen Defaults (SSE kann keine komplexen Params)
Fixes:
- "Connection to server lost" bei Analyse-Ausführung

Frontend:
- api.js Zeile 499: BASE_URL → BASE (executePromptStreaming)
- nginx.conf: proxy_read_timeout 300s für lange Workflow-Ausführungen
Fixes:
- "BASE_URL is not defined" Fehler in Analyse-Seite
- 504 Gateway Timeout bei Workflow-Ausführung (>60s)
