AI API Proxy Error Handling

async function makeRequest(url, options, retries = 3) { for (let i = 0; i < retries; i++) { try { const response = await fetch(url, options); if (response.ok) return response; // Don't retry client errors if (response.status < 500) throw new Error(`HTTP ${response.status}`); } catch (error) { // Exponential backoff await new Promise(r => setTimeout(r, 2 ** i * 1000)); } } // Fallback to backup provider return fallbackRequest(url, options); }

// 1. Always implement exponential backoff const delay = Math.min(1000 * 2 ** retryCount, 30000); // 2. Never retry 4XX errors (except 429) const isRetryable = status === 429 || status >= 500; // 3. Implement circuit breaker pattern if (failureCount > 5) { return fallbackResponse(); } // 4. Log all errors for debugging logger.error({ status, message }, "Request failed"); // 5. Provide meaningful error messages throw new Error(`AI request failed: ${statusText}`);
