    3. Advanced Error Handling

    Build resilient workflows with retry and recovery patterns.

    15m Lesson 3 of 5

    Production workflows must handle failures gracefully. Learn patterns that keep your automations running even when things go wrong.

    Code Examples

    Retry with Exponential Backoff (Code Node)
    javascript
    // Implement custom retry logic
    const maxRetries = 3;
    const baseDelay = 1000; // 1 second
    
    for (let attempt = 1; attempt <= maxRetries; attempt++) {
      try {
        // Your API call here
        const response = await $http.request({
          method: "GET",
          url: "https://api.example.com/data"
        });
        return [{ json: response }];
      } catch (error) {
        if (attempt === maxRetries) throw error;
        const delay = baseDelay * Math.pow(2, attempt - 1);
        await new Promise(r => setTimeout(r, delay));
      }
    }

    Pro Tips

    • 💡Use the built-in "Retry On Fail" option on nodes before writing custom retry logic
