Raw Blame History

CompetenceTrack — Project Worklog

Task ID: 1 Agent: fix-auth-500-and-session-issues Task: Fix Auth 500 Errors and Session Persistence Issues Date: 2025-01-28

Work Log:

Session persistence fix (src/lib/auth.ts + src/app/api/auth/route.ts):
- Root cause: cookies().set() from next/headers may not reliably propagate the Set-Cookie header to the NextResponse body in Next.js App Router route handlers.
- Fix: Added response.cookies.set() on the NextResponse object for login, register, and logout actions, guaranteeing the cookie is sent.
- Added isSecureRequest(request) helper that checks x-forwarded-proto: https header (for HTTPS proxies like sslip.io) in addition to NODE_ENV === 'production' to determine the Secure cookie flag.
- Exported SESSION_COOKIE_NAME, SESSION_COOKIE_MAX_AGE, and getSessionCookieOptions() from auth.ts so the route handler can set cookies on the response with consistent options.
- createSession() now accepts an optional secure parameter.
Excessive GET /api/auth 401 polling fix (src/app/page.tsx):
- Added a useRef(false) guard (hasCheckedRef) to the auth-check useEffect so it only fires once per component lifecycle, preventing duplicate or repeated calls.
Rate limit increase (src/lib/rate-limit.ts + src/app/api/auth/route.ts):
- Auth POST rate limit: 20 → 30 req/min.
- Auth GET rate limit: 60 → 120 req/min (in both the RATE_LIMITS.authGet preset and the inline checkRateLimit call in the GET handler).
- Added authGet preset to RATE_LIMITS for future use.
Better error handling (src/app/api/auth/route.ts):
- POST catch block now distinguishes Zod validation errors, Prisma/database errors, and generic errors, returning specific messages and status codes.
- GET catch block now includes the error message in the response body for debugging.
- Error logs use Auth POST error: and Auth GET error: prefixes for easier log filtering.

Task ID: 2 Agent: fix-script-tag-warning-module-factory-error Task: Fix Script Tag Warning and Module Factory Error Date: 2025-01-27

Work Log:

Fixed script tag warning in chart.tsx:
- Replaced <style dangerouslySetInnerHTML={{...}}> with <style ref={(el) => { if (el) el.textContent = cssText }} /> in the ChartStyle component
- This avoids React 19's "Encountered a script tag" warning that is triggered for style elements using dangerouslySetInnerHTML
- The ref-based approach sets textContent synchronously during the commit phase, so no FOUC occurs
Improved sanitizeHtml function in utils.ts:
- Replaced the fragile [^<]* regex pattern with [\s\S]*? (non-greedy, matches any character including newlines)
- Added handling for unclosed <script> tags (no closing tag)
- Added handling for self-closing <script /> tags
- Added removal of <noscript> tags (may contain script-like content)
- Added removal of <link> tags (could load external scripts)
- Added removal of <meta> tags with http-equiv="refresh" (could redirect)
- Updated iframe, object regex patterns to use [\s\S]*? for multi-line support
Fixed module factory error in service worker:
- Bumped cache version from v2 to v3 to force cache invalidation
- Added a dedicated /_next/ path check that uses NetworkOnly strategy (never caches)
- This prevents stale Turbopack chunks from being served, which cause "module factory is not available" errors
- Comment explains why /_next/ paths must never be cached
Updated offline-indicator.tsx useServiceWorker hook:
- Added process.env.NODE_ENV === 'development' check to skip service worker registration during development
- This prevents the service worker from interfering with Turbopack's hot module replacement
- Service worker is only active in production builds
Verification: bun run lint passes with 0 errors
