## Summary
- Fixes Railway deployment build failures caused by dynamic server usage
errors
- Marks routes that use runtime features as `force-dynamic` to prevent
static generation attempts
- Creates proper error pages to handle 404/500 scenarios
## Problem
The build was failing with "Dynamic server usage" errors because Next.js
was trying to statically generate pages that use runtime features like:
- `cookies()` for authentication
- `searchParams` for filtering
- Dynamic data fetching that requires request-time context
## Solution
Added `export const dynamic = 'force-dynamic'` to:
### API Routes
- `/api/jobs/route.ts` - uses searchParams
- `/api/jobs/skills/route.ts` - uses cookies via fetchFromApi
- `/api/version/route.ts` - uses cookies via fetchFromApi
- `/api/raids/groups/route.ts` - uses cookies via fetchFromApi
- `/api/parties/route.ts` - uses searchParams and cookies
- `/api/parties/[shortcode]/route.ts` - uses cookies
- `/api/parties/[shortcode]/remix/route.ts` - uses cookies
### Page Components
- `/app/[locale]/teams/page.tsx` - uses searchParams
- `/app/[locale]/new/page.tsx` - fetches dynamic data
- `/app/[locale]/saved/page.tsx` - uses cookies and searchParams
- Additional pages to avoid useContext errors during static generation
### Error Handling
- Created `/pages/_error.tsx` - Simple error page without i18n
complexity
- Created `/app/not-found.tsx` - App Router 404 page
## Test plan
- [x] Build completes successfully locally with `npm run build`
- [ ] Deploy to Railway staging environment
- [ ] Verify all dynamic routes work correctly
- [ ] Check error pages display properly

## Summary
- Fixes periodic production crashes (undici ECONNREFUSED ::1) by
bounding server cache size/lifetime and hardening server HTTP client.
### Root cause
- React server cache (cache(...)) held axios responses indefinitely
across many parameter combinations, causing slow memory growth until the
Next.js app router worker was OOM-killed. The main server then failed
IPC to the worker (ECONNREFUSED ::1:<port>).
### Changes
- `app/lib/data.ts`: Replace unbounded cache(...) with unstable_cache
and explicit keys; TTLs: 60s for teams/detail/favorites/user, 300s for
meta (jobs/skills/accessories/raids/version).
- `app/lib/api-utils.ts`: Add shared Axios instance with 15s timeout and
keepAlive http/https agents; apply to GET/POST/PUT/DELETE helpers.
- `pages/api/preview/[shortcode].ts`: Remove duplicate handler to dedupe
route; retain the .tsx variant using `NEXT_PUBLIC_SIERO_API_URL`.
### Notes
- Build currently has pre-existing app/pages route duplication errors;
out of scope here but unrelated to this fix.
- Ensure `NEXT_PUBLIC_SIERO_API_URL` and `NEXT_PUBLIC_SIERO_OAUTH_URL`
are set on Railway.
### Risk/impact
- Low risk; behavior is unchanged aside from bounded caching and
resilient HTTP.
- Cache TTLs can be tuned later if needed.
### Test plan
- Verify saved/teams/user pages load and revalidate after TTL.
- Validate API routes still proxy correctly; timeouts occur after ~15s
for hung upstreams.
- Monitor memory over several days; expect stable usage without steady
growth.
