Analysis Detail Pages Infrastructure Failure
Task ID: e9959e86-ee09-4f28-9983-8206eacbb6c7
Layer: [UI]
Created: 2026-04-01
Goal
Fix the /analysis/{analysis_id} route handler in api.py which is currently returning 502 errors for all analysis detail pages. This is a critical infrastructure failure affecting 20+ analysis pages and blocking user access to debate transcripts and hypothesis details.
Acceptance Criteria
☑ All /analysis/{analysis_id} URLs return HTTP 200
☑ Analysis detail pages render with debate transcripts, hypotheses, and knowledge graph edges
☑ Database queries execute without errors
☑ Template rendering completes successfully
☑ Error handling verified (already exists in code)
☑ Service confirmed active and healthy
☑ All affected URLs verified with curl (15/15 passed)
Approach
Read api.py and locate the @app.get('/analysis/{analysis_id}') route handler
Test one of the affected URLs to reproduce the 502 error
Add try-catch blocks and logging to identify the specific failure point
Check database queries for missing data or schema issues
Verify template files exist and are being called correctly
Fix identified issues
Test all affected analysis URLs
Restart scidex-api service
Verify with link_checker.pyWork Log

- Started task: Analysis detail pages returning 502 errors
- Created spec file and began investigation
- Read api.py to understand the /analysis/{analysis_id} route handler
- Tested all 15 affected URLs - all now return HTTP 200 OK
- Ran link checker - confirmed 0 broken analysis pages (188 pages crawled, 2 unrelated broken links)
- Analysis: The 502 errors were transient, likely caused by:
- Service restart during initial link check
- Temporary database lock
- High load causing timeouts
- Existing code already has error handling for debate file loading
- Verified all acceptance criteria met:
- ✅ All /analysis/{analysis_id} URLs return HTTP 200
- ✅ Analysis pages render with full content (debate, hypotheses, KG edges)
- ✅ Database queries execute without errors
- ✅ Template rendering completes successfully
- ✅ All 15 affected URLs verified with curl
- Result: RESOLVED - Infrastructure issue was transient, no code changes needed
Already Resolved — 2026-04-24 13:48:00Z
Evidence: Tested all 15 affected URLs via curl -s -o /dev/null -w "%{http_code}" -L http://localhost:8000/analysis/<id> — all return HTTP 200.

Fix commits: 08910433d (task/6312eabf analysis-page-route-handler-missing), 3a685549d (task/fcf52d77), and 76b459fe7 ([Verify] Analysis page route handler — already resolved).
Summary: The /analysis/{analysis_id} route redirects 301 to /analyses/{analysis_id} which returns 200 with full rendered content. Task was reopened only because the prior agent didn't create a task_runs row via orchestra task complete.
