🔧 Troubleshooting

Setup Script Issues

If you encounter errors with the setup scripts:

Test your environment first:
```
node test-setup.js
```

Common issues and solutions:

Docker not running:

# Start Docker Desktop (Windows/macOS)
# Or start Docker daemon (Linux)
sudo systemctl start docker

Permission issues (Linux/macOS):

sudo chmod +x setup-development.sh
sudo chmod +x mobile/setup-project.sh

Node.js version issues:

# Install Node.js 18+ from nodejs.org
# Or use nvm:
nvm install 18
nvm use 18

Docker Compose not found:

# Install Docker Compose
# Or use the newer 'docker compose' command

Manual setup if scripts fail:

# Create directories
mkdir -p backend/api-gateway/logs
mkdir -p backend/payment-service/logs
mkdir -p backend/verification-service/logs

# Install dependencies manually
cd backend/api-gateway && npm install
cd ../payment-service && npm install
cd ../verification-service && npm install
cd ../../mobile && npm install

# Start services
docker-compose up -d --build

Service Health Issues

If services fail to start:

# Check service logs
docker-compose logs api-gateway
docker-compose logs payment-service
docker-compose logs verification-service

# Check service status
docker-compose ps

# Restart specific service
docker-compose restart [service-name]

Mobile App Issues

If mobile setup fails:

cd mobile

# Clear everything and retry
rm -rf node_modules package-lock.json
npm cache clean --force
npm install

# Fix React Native issues
npx react-native doctor
