Overview

Proper error handling is critical for building robust applications with ZKScore. This guide covers common errors, handling strategies, and recovery patterns.

​
Common Errors

​
API Errors

try {
  const score = await zkScore.getScore(identity);
} catch (error) {
  if (error.code === 'IDENTITY_NOT_FOUND') {
    console.error('Identity does not exist');
  } else if (error.code === 'RATE_LIMIT_EXCEEDED') {
    console.error('Rate limit exceeded, please retry later');
  } else if (error.code === 'INVALID_API_KEY') {
    console.error('Invalid API key');
  } else {
    console.error('Unexpected error:', error.message);
  }
}

Best Practices

  1. Specific Handling: Handle each error type specifically
  2. User Feedback: Provide clear error messages
  3. Retry Logic: Implement exponential backoff
  4. Logging: Log errors for monitoring
  5. Graceful Degradation: Continue with limited functionality
