Troubleshooting

Chromium not found

cd server
npx playwright install chromium
npx puppeteer browsers install chrome

No results from Google Maps

Google has stricter bot detection. Try increasing delays in google-maps-scraper.ts or run with headless: false to debug.

JustDial phone numbers missing

Phone numbers are behind "Show Number" buttons. Check console logs for click failures — modal selectors may have changed.
