In `@vercel.json`:
- Around line 6-11: The catch-all rewrite rule mapping source "/(.*)" to
"/index.html" is routing API calls (like the serviceWorker fetch to
"/api/push/subscribe") to the SPA HTML; update the rewrites so API routes are
excluded (allowing requests under "/api/*" and other backend paths to pass
through) by modifying the rewrites block—keep the existing rewrite for
client-side routes (destination "/index.html") but add a higher-priority rule or
exclusion for "/api/{path*}" (and any other backend prefixes) so the
"/api/push/subscribe" endpoint receives normal API requests instead of HTML.

Critical: Catch-all rewrite breaks the /api/push/subscribe endpoint.
The current rewrite rule routes all requests to /index.html, including the relative fetch call to /api/push/subscribe in frontend/src/utils/serviceWorker.ts. This will cause the push notification subscription to fail because the endpoint will receive HTML instead of a proper API response.
🔧 Proposed fix to exclude API routes from the rewrite
"rewrites": [
+ {
+ "source": "/api/:path*",
+ "destination": "/api/:path*"
+ },
{
"source": "/(.*)",
"destination": "/index.html"
}
]This ensures API routes are passed through to the backend while all other routes are handled by the SPA for client-side routing.
