Laravel loaded, but public/build/.vite/manifest.json was not found or has no entry for src/main.tsx.
On the server, build and copy the Vite output:
cd portal/frontend npm ci npm run build mkdir -p ../public/build rm -rf ../public/build/* cp -a dist/. ../public/build/
Use cp -a dist/. (not cp dist/*) so the hidden .vite/ manifest is copied.
Also ensure APP_ENV=production (not local) so the app does not try to load scripts from localhost:5173.
