🐛 Troubleshooting:

Common Issues:

Development Build Required:

  • Video features require native code
  • Cannot run in Expo Go - must use development build
  • Run eas build --platform ios --profile development

Permissions Not Granted:

  • Camera permission required for video recording
  • Microphone permission required for audio
  • Media library permission for saving videos

Video Not Recording:

  • Check camera device availability
  • Ensure proper permissions granted
  • Verify react-native-vision-camera installation
  • Check development build includes native modules

Upload Failures:

  • Verify Supabase videos bucket exists
  • Check internet connection for cloud upload
  • Ensure user is authenticated
  • Run video-database-setup.sql if tables missing

Debug Commands:

# Check native module installation
npx expo install --check

# Rebuild development build
eas build --platform ios --profile development --clear-cache

# Check app.json plugin configuration
cat app.json | grep -A 10 "react-native-vision-camera"
