[web] Fix server crash on unmatched routes by VaguelySerious · Pull Request #1590 · vercel/workflow

VaguelySerious · 2026-04-02T16:19:46Z

Summary

Adds ErrorBoundary export to the root route so React Router renders 404s gracefully instead of failing during SSR
Adds Express error-handling middleware as a safety net to catch any errors that escape the React Router error boundary
Adds tests for the ErrorBoundary component

Test plan

Unit tests for ErrorBoundary (404 and generic error states)
Manual: run workflow web, request /robots.txt — should get a 404 page, not a crash

🤖 Generated with Claude Code

…utes Fixes workflow web crashing (process.exit(1)) when requests hit URLs without a matching React Router route (e.g. /robots.txt, /favicon.ico). - Add root ErrorBoundary so React Router renders 404s gracefully - Add Express error-handling middleware as a safety net for SSR failures Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

AI review: Approve — correct fix, proper defense-in-depth, no regression risk.

Two-layer approach is solid: Root ErrorBoundary handles the primary case (React Router renders 404s gracefully), Express error middleware catches anything that escapes SSR. Standard patterns for both.
ErrorBoundary renders outside theme/nav context since it's the root boundary — the minimal fallback styling is appropriate here.
Tests cover the important shapes: 404 route error, generic Error, 500 route error, and link target verification.
