fix: render course pages dynamically to avoid production 500#260
Merged
Conversation
The course page reads searchParams (?year=) but declared the static- generation config (generateStaticParams + revalidate=false) copied from /race/[slug]. Touching searchParams in a statically-generated route throws DYNAMIC_SERVER_USAGE at request time, 500ing every /courses/[course] page in production (dev masked it — dev always renders dynamically). Opt into dynamic rendering instead. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01LFeozH85YsXjHHbE79Jqs3

The PR-open push did not create a Vercel deployment (likely a dropped webhook during a GitHub 503 window), so the required Vercel status never posted and the PR stayed blocked. Empty commit to re-fire the deployment. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01LFeozH85YsXjHHbE79Jqs3

Motivation
Every
/courses/[course]page (added in #259) returned a 500 in production — e.g.https://www.tritimes.org/courses/im703-melbourne.Root cause
The page reads
searchParams(?year=) but declared the static-generation config (generateStaticParams+revalidate = false) copied from/race/[slug]. TouchingsearchParamsin a statically-generated route throwsDYNAMIC_SERVER_USAGEat request time, 500ing the page. Dev masked it (dev always renders dynamically); only the production build (which classified the route● SSG) failed./race/[slug]is unaffected because it never readssearchParams.Fix
Opt the route into dynamic rendering (
export const dynamic = "force-dynamic") instead of static generation, since it must be request-time to read?year=. The route now builds asƒ (Dynamic).Testing
Reproduced and verified in production mode (
npm run build && npm start), which is what CI/dev missed:/courses/[course]→ 500 (DYNAMIC_SERVER_USAGE).?year=2023→ 200, nonexistent course/year → 404, zero server-render errors.Note: CI runs
npm run build(which succeeds even with the bug, since the error is request-time) but not a production-mode smoke test, so neither CI nor the dev-mode Playwright e2e caught this. Documented the invariant in a code comment to prevent reverting to the static config.🤖 Generated with Claude Code
