WAVE 112 AGENT 13: DATETIME TYPE ERRORS - SQLX CACHE REGENERATION
==================================================================
MISSION: Fix 11 DateTime type errors by regenerating SQLx cache
STATUS: ✅ SUCCESS - All errors resolved in ~10 minutes
ROOT CAUSE:
-----------
1. SQL Syntax Error (PRIMARY):
- File: services/api_gateway/src/auth/mfa/mod.rs:440
- Issue: Type annotation in INSERT statement (only valid in SELECT)
- Fix: Removed `as "expires_at: chrono::DateTime<chrono::Utc>"` from INSERT
2. Stale SQLx Cache (SECONDARY):
- Old cache had incorrect type mappings
- Solution: Regenerated with live database connection
RESOLUTION STEPS:
-----------------
1. ✅ Verified PostgreSQL running (docker-compose up -d)
2. ✅ Confirmed database connectivity (psql SELECT 1)
3. ✅ Fixed SQL syntax error (removed type annotation from INSERT)
4. ✅ Regenerated SQLx cache (cargo sqlx prepare --workspace)
5. ✅ Verified compilation (SQLX_OFFLINE=true cargo build)
RESULTS:
--------
- Compilation Errors: 11 → 0 (-11 ✅)
- DateTime Type Errors: 11 → 0 (-11 ✅)
- SQLx Cache Files Generated: 11 query metadata files
- Build Time (offline): 0.28s ✅
- Build Status: SUCCESS (0 errors, 9 warnings)
FILES MODIFIED:
---------------
1. services/api_gateway/src/auth/mfa/mod.rs (1 line - removed type annotation)
2. .sqlx/query-*.json (11 cache files - regenerated)
KEY LEARNINGS:
--------------
- SQLx type annotations: SELECT ✅ | INSERT ❌ | UPDATE/DELETE (inferred)
- Always regenerate cache with live database connection
- Use SQLX_OFFLINE=true in CI/CD to avoid database dependency
- Commit .sqlx/ to version control for reproducible builds
NEXT STEPS:
-----------
- Address 9 warnings (cargo fix --lib -p api_gateway)
- Proceed with remaining Wave 112 compilation fixes
- Coverage measurement (after all compilation errors fixed)
